Metz mecablitz 44 AF-2 Digital Flash for Pentax Cameras - any comments?

2018-07-27 Thread luiz felipe
looking at the pc screen, the  Metz mecablitz 44 AF-2 Digital Flash for 
Pentax Cameras looks interesting due to low price, advertised P-TTL 
compatibility and "adjustable four level video light". the cash, as 
always, is rather short so no option more expensive than the AF360FGZ II 
is coming home - but IF this or another Metz is adequate, more $$ can be 
diverted to lenses and cameras.


from my previous experience with Pentax flashes (280t and 330ftz) they 
tend to eat batteries faster than ideal, but had endured a lot of abuse. 
the 360 FGZ II is weather resistant, but that's not to be an issue - I 
don't intend to take flash photography under the rain. flash photos are 
not so frequent, for me, to the point a Vivitar 285hv has been enough 
until now.


any toughts? any hands-on experience with the "video light" of those 
two flashes? FWIW, I do carry a flashlight in the bag all times, and 
have used it on occasion to light my subjects under very low light - the 
feature is welcome indeed.


thanks in advance!

Re: Vixen Polarie - not Pentax, but I'll use with Pentaxes - any toughts?

2018-06-10 Thread luiz felipe
Darren,there are some issues with this idea indeed. but I'm willing to 
try.


calibration is performed by rolling the unit on 3 axes, isn't it? IF 
the communication between O-GPS and camera works through the extension, 
maybe rolling the connected unit before attaching to the telescope is 
possible. the reverse position of the image and how the sensor should 
move to keep proper framing is something I didn't think about until now 
- IMO a test is the best way to see what will happen. maybe the 
communication fails with the cable.


anyway, since I don't have the telescope right now, I'm going for the 
O-GPS1 - and adding a TTL extension just to see what happens. even the 
smaller tracking time of the O-GPS will be an improvement to what I can 
do today - should  allow me to lower the ISO and get cleaner images.


Thank you for the comments - will post any results, later. even 
receiving "imported goods" here in Brasil is a challenge.

Your TTL idea would be unnecessary on a refractor, so you must be 
thinking

of using a Newtonian design. In that case I don?t think it would work
because the image is reversed. I think the program in the O-GPS would 
be
designed to shift the sensor in only one direction (the one that work 
with

ordinary camera lenses of a refractor-sort of design). Not sure though.

Also, keep in mind that the maximum exposure time possible with the
O-GPS/AstroTrack gets shorter and shorter as the focal length gets 
longer.
A shorter exposure time with a longer focal ratio is the opposite of 
what

you want for catching photons in astrophotography.

Respectfully,
Darren Addy

2018-06-09 Thread luiz felipe
Darren, Larry, thanks for your toughts - precisely the kind of info I'm 
looking for, from hands-on knowledge.


Darren, I have used my phone's level and a compass to set the camera 
for Iridium trail photos and to look for comets, and am near the equator 
- no real need for a latitude wedge, just some tripod leg tuning until 
I'm close to 4deg tilt in the right direction. since I intend to keep 
the exposures as short as possible (yet longer than my current 2 sec 
limit), some small errors should be acceptable - and from what I 
understand, the Polarie is not plagued by the tracking error a 
tangential barn door drive is famous for. the need to manually track 
between exposures with the O-GPS is part of the reason why I am 
interested in the Polarie/ barn door drive, added to the possible use of 
a smallish reflector.


the calibration proccess - in theory - does not frighten me. I will 
have a setup to make either way. one question, for you users - this 
O-GPS 1 calibration holds with the camera sleeping (not off but after 
the metering time-out)? for me, the best about the O-GPS is both size 
and faster setup/ calibration - or am I wrong about the real world 
calibration?


last night, talking to Larry, it did pass my mind a curious notion - 
that **IF** the O-GPS1 actually communicates with the camera by means of 
the flash contacs, **AND ASSUMING** said comm would still happen through 
a TTL flash cable, would it be possible to align the O-GPS1 with a 
telescope tube and get the correct tracking? context: under 1000mm 
tubes, most likely in the 500 to 650mm. anyone with the O-GPS and a TTL 
flash extension willing to make a field test?? it could also open the 
way to some sideways traking and curious images.


thanks yet again, and not only for the ideas, those pics ARE 
outstanding!!!

Subject: Re: Vixen Polarie - not Pentax, but I'll use with Pentaxes -
any toughts?

I have the Vixen Polarie. I had an O-GPS1 for a time, but sold it. I 
now

have the AstroTrack built into the K-3ii.
The biggest differences are:

No annoying calibration necessary with the Polarie, but it must be 
polar

aligned. (I built an adjustable wedge for the latitude part of the
equation, so if your tripod is level and the wedge angle correct, the 
only

thing you need to dial in is the azimuth alignment.)
https://flic.kr/p/pVVUTv

Both systems will face limitations at longer focal lengths, but you 
can do
a lot with 200mm or less. This was taken with a 90mm Tokina AT-X macro 
on

the jankity set-up above.
https://flic.kr/p/qzf4Xi

The O-GPS will track during an exposure, but the camera will need to 
be
repositioned as the earth?s rotation moves it out of frame. The 
Polarie
will track the object whether you are taking exposures or not (meaning 
you
can use an intervalometer to take multiple exposures (for later 
stacking,

for example)

I think the biggest problem with my current Polarie set-up is flex. 
Even
with a high quality ball head, it can be frustrating to think you have 
your
object framed properly, tighten the bullhead down, let go, and find 
your
object is no longer framed as you like. This problem gets greater the 
more

weight you try to hang of of it.

Both solutions are more for wide field astrophotography. But nice 
things
can be done with the O-GPS and the DA* 200mm f2.8 as this French 
Pentaxian

shows:
http://poirierstephane.free.fr/photos/index.php?/category/132
However, it is worth pointing out that the same lens on a polar 
aligned

Polarie could achieve the same results.

Hope this helps.

Has anyone been getting any photos of Comet Lovejoy?

2015-01-06 Thread luiz felipe
I'm not that happy with mine, but I managed twice from urban zones and 
cloudy nights. the bright sky makes it impossible to spot it with naked 
eyes and ruins color details, so I went for the moderate tele field, 
looking for the fuzzy green - then I switch to longer lens if the clouds 
allow it. way easier said than done.


no tail so far - but from now on, things will improve as the Moon is 
past full, rising each night later and farther from the comet. I'm 
currently keeping an eye at weather, tripod/ camera/ outdoors tools at 
the ready. getting a proper picture requires dark sky at night - away 
from urban zones.

Bruce, make and model duly noted, I'm currently thinking about one that 
would be fixed over the LCD - but it's good to know about your option.


Brian, I'll use mostly my (m)K and Takumar stuff with the K adapters, 
no DA for the moment. the tripod socket should help as the camera's may 
be filled with the shade, but I guess some of my lenses qualify as 
heavy. more thought required...

2014-12-21 Thread luiz felipe
I am thinking about a Pentax Q lately, to get the extra-long lenses 
that result from the sensor size added to our ordinary glass. after 
some reading, and some looking at pictures taken with the camera, I am 
stuck at two last details: a shade/ loupe for the LCD, and an adapter 
for the K lenses.


first question: do any of you happen to use a particular model and 
brand of shade over your Q - or over any other camera - and would care 
to comment about attachment and quality?


second: there are some adapters for K lenses being advertised, what 
kind of features should I be looking for? aperture control? tripod 
socket? most of my lenses have aperture ring, so I my choose a cheaper 
model, right?


thanks in advance!

help wanted, doubts about 200mm by Pentax

2013-08-05 Thread luiz felipe

thanks P.J.

I had little luck with 70-210 by Takumar (M42) and Pentax, but probably 
because both lenses were rather banged when I got them. used for a short 
while a diff 70-210 sample that I remember as good, but being a borrowed 
lens I never got to test it.


I'll be quickly testing the SMC-M next week, and probably I'll trade. 
these nights I'll be testing the 80-320, the SMC Takumar 200mm/4 and 
whatever other long lens I gather against a far wall with tiles and 
street lamps. if possible, I'd test both 200mm with this scene, but 
don't think this will be possible. we'll see...

help wanted, doubts about 200mm by Pentax

2013-08-02 Thread luiz felipe
in particular, I am wondering about two lenses: the Super-Multi-Coated 
Takumar 200mm f/4 and the SMC-M Pentax 200mm f/4. I own the Takumar, and 
a very good and clean one bought from a friend some time ago. I do like 
this lens, sharper than others in that range but somewhat less contrasty 
than I'd like. yesterday I've been offered a supposedly good copy of the 
SMC-M 200mm/4, in exchange for my Tak, some small cash adjustment 
possible.


I used one of those long ago, and from Boz's site I confirmed the M is 
quite smaller and lighter than the SMC Tak. main advantage for me would 
be the release of the Tak's M42 adapter - I am one short right now - 
with size and weight smaller bonuses. but I'd rather keep the sharpest 
of them above all other considerations. I'll be seeing the M in a few 
days, to get a proper idea of its condition, but would like to know from 
you folks wich would be better. From Fred's site I got one praise for 
the SMC-M, but I would really like to read from anyone with hands-on on 
both, if possible, or at least a sample shot from the SMC-M so I can 
understand better my options. sadly, I don't think I'll be able to 
perform a full comparison before the deal - just a couple of shots to 
ensure the SMC-M is working good, and the other interested will probably 
do the same with my Takumar.


so, what do you think about those lenses? wich should I choose, if both 
are perfect? thanks in advance!

Orion Starblast vs 500mm mirror

2013-01-08 Thread luiz felipe

Darren's words:
Tried the Orion Nebula with the 135/2.5 - too clear skies, lots of 
clouds,

bad results - and purple fringing.


I got to thinking that maybe you are referring to the Bayonet 135/2.5.
If so, the purple fringing is certainly understandable.
I'm talking about the last version of the Super-Multi-Coated Takumar
135mm f2.5, which also then became the original SMC K version (not the
same as the later Bayonet version).

The Bayonet version is a $50-60 lens. The v2 Takumar  SMC K version
are more like $175-225 but bargains can be found.



Darren, I'm talking exactly about the SMC Tak 135/2.5, m42  58mm 
filters. Mine gets purple fringes wide open, not so intense but 
noticeable. It's also rather battered, much used since 1976. Bought a K 
Takumar 135/ 2.5 but still got to test it - someday soon, not in a 
hurry... it's expected to be less than outstanding but useable. I'd 
delay my astro enablements if a VG K135/ 2.5 came my way... really like 
that lens and mine is getting old.


I'm trying to repeat photo and processing, and re-processing the first 
test - did it quickly and didn't enjoy the results.

Orion Starblast vs 500mm mirror

2013-01-08 Thread luiz felipe

Jostein's words:

Hi Luiz,
My experience so far does not cover your alternatives, but I dare a 
comment

anyway.

I would suggest you find a manual focus mirror tele lens to try out 
first
since it's the cheapest option and since it probably is easier to sell 
again

if it proves to be the wrong choice.

I've done a couple of astrophotos with the K-5 and the O-GPS-1, and 
can
vouch for its convenience. But then again I'm a noob at astrophoto... 
:-)


Jostein



Glad you mention it, Jostein... been wondering about wich 500mm tele 
would you use in this scenario. The selling a failure idea is very 
interesting indeed - the fact some lens didn't work for me does not mean 
it won't be useful somewhere else. Come to think of it, the 500 mirror 
is probably easier to arrive safely and cheaper to ship... hmmm... I 
think I saw some 500mm f/6- somewhere.

Orion Starblast vs 500mm mirror

2013-01-07 Thread luiz felipe

Steve's words:

For an astronomical telescope, f8 is not that slow.
Schmidt-Cassegrains - the most popular off the shelf optical system -
are usually f10 (though focal reducers are available). I think what's
more important is the optical quality of the lens. A lot of those
inexpensive mirror lenses are not very good.

As for astrophotography with the O-GPS1...I've gotta get one!

Steve Sharpe



Steve, those reflectors have been quoted as useable and entry-level 
by some. Orion's Starblaster gets cheaper as it comes without tube rings 
and we provide the mount - fine with me. Didn't browse other brands but 
that model in particular is not too long (optically) nor too dark and 
better some useable tool at hand than a proper in the store. So much 
for theory... and of course I'd add the O-GPS1 too as soon as possible!

Orion Starblast vs 500mm mirror

2013-01-07 Thread luiz felipe

Darren's words:

I know that f/8 is not unusual for a visual scope. (my 8 dob is f5.9)
But f/8 is still f/8 photographically (exposure-wise).

We've also switched subjects (more than a little) slightly when we are
talking about using the telescope as the lens to the camera. That's
called prime focus photography and it means that the projected image
will need to reach the DSLR sensor (with no lens attached). I'm not
wild about leaving my DSLR sensor exposed to the elements for any
longer than necessary, but that's what you are doing when you use it
on a reflecting telescope (as opposed to a catadioptric which is
sealed like an over-sized mirror lens). You also need to have a way to
really lock down that telescope focuser because it would be great
(not) if the focusing tube with camera body attached worked its way
right out of the focuser. And you are still back to the issue I
originally raised as to How Good/Accurate the tracking unit is on the
telescope you are mounting it on. Because now you are effectively
using the focal length of the telescope the same as you would a lens.
On my 8 dob that is 1200mm. Every step better be smooth or you are
going to have a vibration. You also need to be perfectly polar-aligned
or you will have issues with longer exposures.



In short, prime focus photography is not done cheaply or easily. You
should certainly cut your teeth on something easier and work your
way up as you learn the various pieces of the puzzle.


Well put. Some of those points I'm thinking about since december. the 
support question - since the Starblast comes without rings I've been 
thinking about a craddle, and imagined a support for the camera, 
something able to take the weight out of the adapter and yet allowing 
focusing. Not quite there yet, but some ideas are going to paper 
tonight. Never gave the open air condition a tought until now - but 
there is no way to avoid it, other than using a Barlow - not in my 
plans, really... as for the tracking unit... as soon as I finish it, 
we'll know. Will be an Isosceles mount, progressive tracking errors not 
relevant since I intend to keep exposures under 5 minutes and start from 
a closed unit. Do not plan to hand-turn it... and am very worried about 
motor and train vibration.


FTR, the Starblaster is listes as 450mm, f/4 - not so long, not so dark 
- if only it turns out good...

Which bodies are worth keeping?

2013-01-03 Thread luiz felipe

Larry's words:
I'm attempting to do a much needed cleanup of the closet that I use 
to

keep my photo and camera gear.
A few years back I used to peruse craigslist for interesting Pentax 
gear.

A lot of the interesting lenses came with film bodies. Plus, I got a
couple from my mom.  As such, I've got an assortment of film bodies 
that
I've never even used.  I'll want to keep one or two, just because, 
but
should find better homes for the rest.  Since all of my Pentax 
experience
was either with a Spotmatic or DSLRs, I don't know much about K-mount 
film

bodies.

So, what are the relative merits of?:
ZX-10  (AF)
ZX-50  (AF)
Super Program (AE?)
P30t (AE?)
P5   (AE?)
MEsuper
K1000

I'd guess that the two worth keeping would be the K1000, for 
simplicity,

and the ZX-50 for features.


Larry, the only Mz/ Zx bodies I'd be interested in would be the 3 and 
the 5n, and I'd think twice since the 5 viewfinder is smaller and hard 
to use in dim light. The K1000 may be praised by many, but I'd let it go 
- almost no info on the finder, lightmeter always on and rather big 
size. The Me Super I'd possibly keep as disposable camera *if* paired 
with a cheap but useable lens, otherwise sell it since the Super Program 
would be staying. The P's would go too, just because the Super Program 
would be staying. Any of those 3 could be staying otherwise, Me Super 
last to go.


I'd try to keep the Super Program due to its features, small size and 
interesting viewfinder. Assuming all cameras in the same condition, of 
course. Now if you had a Mx or a Lx... those are Keepers, Capital K, 
IMHO. That said, if you decide otherwise I'd give the Super Program a 
good home (no pressure).


By all means, choose the one you feel like using, or the one you feel 
more attached to, or both if you feel like using one and like the 
other's history.

FS: Two Sigma 24mm f/2.8 Super-Wide II lenses (one AF, one MF)

2012-12-15 Thread luiz felipe
Joe, that exposure correction matches my findings on one sample Sigma 
AF 24mm 2.8, with MZ5, PZ70, PZ1p, Mx and Lx (both Mx and Lx needed no 
correction at all). Wrong maximum aperture reported to the camera was 
tought to be the problem back then.


Cheers,

lf

Joe's words:
The AF lens seems to need a -1.0 EF adjustment on most Pentax digital 
bodies; the MF lens needs -1.3 EF or so (this seems to be typical of 
Sigma lenses from the film era on current Pentax bodies?)

semi-OT: Leonid meteor shower this weekend, heads - and cameras - up.

2012-11-17 Thread luiz felipe
Drove some 130km in search of a better place - Fortaleza is a city of 
light, unsuitable for any kind of astrophotography. Managed to take a 
friend with me - still using Canon but he'll see the light someday.


As soon as we secure the place and start shooting, we get company - a 
donkey came by to check our cameras... and escaped being shot due to my 
rigorous training and the fact we had only a smalish 35cm knife. After 
20 minutes of happy shooting - no meteors but some stars - the clouds 
roll in. Shit!


Spent most of the night waiting, trying other nearby spots with less 
eyewitnesses, and after a while we get a still better place and clear 
skies again... so when the right meteor streaks across clear and 
properly framed Orion I notice the long exposure I set up before 
grabbing a coke had terminated due battery issues... good the donkey was 
not nearby, there was some swearing.


Soon after the second battery is installed, clouds strike again. Time 
for a snack. After some more shots dodging the worst clouds, we gave up 
and drove home.


Balance - 11 meteors, 1 medium and rather good looking, 8 small, 2 
almost invisible - one each photographer. Lots of scared drivers afraid 
of the new mobile radar manned by plain-clothed officers into a 
non-police car, 5 sandwiches and some coke consumed, some astro pix to 
be processed soon, and two very interesting places mapped and ready for 
the next show - december 13/14. Could be a lot worse...

After reading the K5xxx reviews ...

2012-11-02 Thread luiz felipe

Matthew, to John:
On Thu, Nov 1, 2012 at 10:33 PM, John Sessoms jsessoms002 at 
nc.rr.com wrote:



The incremental increase in pixel count  the better auto-focus with
lenses I don't have and am not going to buy don't impress me. Nor 
the
other improvements. The weather resistance would be nice to have 
but

by itself does not add enough value to make me want it.


As somebody who is still stuck with a K10D, what appeals to me most
about the K-5 is none of those things you list; it's the low noise,
high-ISO capability, and dynamic range (three sides of the same coin).
That's what drops my jaw when I see people's K-5 shots. I'm surprised
that you're not even impressed enough to make note of it.




Well I am not telling anyone to buy or not to buy anything but...

Had the money, would gladly trade the Kr for a K30 - street duty, 
everyday - and get a K5IIs for the nights and jobs. Not that I'm not 
happy with said Kr, I like very much my camera... just the newer ones 
would help me now and then, and that's enough for me. Price-wise they 
look good, still cheaper than others and at least equal, usually best. 
Ok, some features shine, some do not - that's life. Since my money is 
scarce and I can use the Kr, I keep it, use it, and try to save. Still 
happy.


I'd also probably have uses for a D600, a 645d, and a new 1911. Cars, 
make mine a Stratos, lime - or maybe a Delta Integrale 16v in silver. Do 
not need them, but feel free to buy me one - even a miniature. Come to 
think of it, my '96 Golf needs front shocks. Cheaper than upgrading 
something I like just because it's old. Newer are safer and offer better 
mileage, so that's why one day I'll replace it. Not in a hurry, unless 
it's a gift. Still happy.


I use Canon and Nikon at least twice a month, could live with them but 
would rather go K30/ K5iis with lenses I currently have and am buying. 
My pics still look mine with other brands, unfortunately there is no 
such thing as *become a better photographer buying brand L*.


D3100's AF faster here, mine still acceptable. XTi getting beaten all 
the time here, still making useful pics. My friends' flashes beat my 
285, but I'm using it so long I only want a better one when I can't 
bounce it. My lenses are better than consumer zooms and kit lenses my 
friends own - main point I'd stay Pentax right now. While I don't buy a 
better flash I bounce my 285 and chimp, while I don't get the new 
cameras I cheat with Noise Ninja. Happy.


Choosing is personal - so when one decides to overlook some advantage 
gear A offers against gear P because P feels better to say aloud, it's 
called freedom. Failing to notice advantages or pretending they do not 
exist are diff matters. Not my problem, actually. Wish you all happy 
(bad if someone would rather so) moments with your dream (or nightmare) 
choices.

Playing with shadows

2012-10-02 Thread luiz felipe
Larry, interesting image(s). I do like it as is, feel the top of the 
bike expands and may perfectly blur as expands. Just me, of course.


You may get sharper shadows and proper light intensity somehow focusing 
the light. One assignment long ago was to cast a perfectly round and 
crisp patch of light on a model - even the bare flash head was too soft 
and the output too weak, so I rented a continuous light cannon and 
managed to project trough the door. The photo can't be shown now (not 
scheduled to scan and post since it was an assignment with clear and 
directed briefing based on previously published fashion shot, not {my 
own idea} image) but the model's shadow is crisp as it gets over the 
background. It does get softer on the far side - but still sharper than 
otherwise.


I remember some fresnel attachments for modifying camera flashes that 
allow wildlife photographers to fill distant subjects. Believe they are 
plastic, not needing to stand modeling lights. My Sinar had a fresnel 
attachment, needed with tilted and shifted wide angles - may be another 
source. Don't know if it will work, maybe you could try to project a 
flash light with a wide angle and normal lenses to prove the concept - 
I'd try it tonight if I get my flashlights to work ;-).


Moving the light source far is a try, but it also would change the kind 
of projection of the shadow - paralel light rays means shadow of the 
same size, distortion provided only by the angle between light, bike and 
the floor. Hey, almost forgot the focus zone of the tilted camera... you 
have some choices to do.


I'm curious, do post the next set.

Larry's light experiments:

When I sit out at night on the bench by the river in my back yard, I 
keep noticing the shadow cast by my bicycle onto the dance floor.  Last 
night, I put my strobe on the upstairs back porch, with the shade to 
direct the light, and got some photos of the shadows cast.   I'm not 
entirely pleased with the results, I'd like sharper shadows all of the 
way around.
I had thought about putting the grid on the strobe, another possibility 
is taking the shade off (almost the opposite) which would make the light 
source smaller, and therfore sharper/harder.  Another possibility would 
be some foil  over the end of a shade with a smaller hold in the middle, 
for an even smaller relative light source.


Has anyone tried something along these lines? Or have other 
suggestions?


For reference, here is a shot from last night:
http://www.flickr.com/photos/ellarsee/8042908138/in/set-72157631665170226

note that the shadows are nice and sharp at the bottom, but a bit fuzzy 
and rough at top.


There are also probably other things I could do by setting the light up 
along the 30-50 foot length of the dance floor and deck, rather than the 
20 foot width, and shooting down from a ladder to get a higher angle.

OT: WinXP boot problems.

2012-10-02 Thread luiz felipe

PJ's nightmare...

On startup the laptop gives the option for a one time boot
menu, which includes all attached bootable devices, including the 
internal
harddrive.  Just for laughs selected the that drive and it boots!  
WTF.



Matthew is probably right, and got there faster, just saw his post

Have you checked in the BIOS that the default boot order is correct
(i.e., has the hard drive first)?

Also, I've had badly-behaved USB devices prevent booting, so if you
have anything attached, try removing it. (That probably even includes
SD cards in an internal reader.)



Possible explanation indeed - based on the boot menu success - the cpu 
was trying to boot a device diff than your hard drive, an incapable one. 
By any chance you had a non-bootable usb or memory card in the pc 
yesterday? Once I used my Linux pendrive on someone's pc and forgot to 
point the first boot to the hard drive later - he called me in the 
middle of night... Got there and removed his pendrive, boot success, my 
fault it was in restoring bios settings.


For the record, I don't think science explains all - if all else fails, 
get some salt in a crystal something, place it in the sunlight, place it 
nearby - then make soft noises with a silver bell and pray... );-)

M42 to K-mount adapter question

2012-09-11 Thread luiz felipe
I started using M42 to Pk adapters almost since the Pk release, have 
used the original version (more than one copy) in KM, K2, Ricoh XR10, 
Lx, Mz5, PZ70, Pz1p and Mx, and never had infinity issues unless the 
camera was off the spec somehow. Yes, that happened with the K2, and 
later with the Lx.


The original adapter by Pentax was designed to remain in the camera 
until a spring was pushed and the adapter released. I almost at once 
fitted the adapter to the lens, removing the spring. Never had one of my 
adapters stuck into the camera, have one that is shallower than the 
others - if I screw it to the end on the lens, the combo will not fit 
into the camera - any camera - so I have it spaced from the lens flange. 
Works fine this way.


Here in BR some home-made adapters appeared lately, but they won't 
focus to infinity - they place the lens farther from the camera. I'd 
stick to original if possible, even spending some $15 extra.


At least one lens - russian made 55mm, can't remember exact model, had 
to be adjusted - the lens had a small, almost cubic appendix that would 
get too deep into the camera (Mx) so I removed it. And also made the 
aperture blades closed by default, since the Mx wouldn't push the 
auto-aperture pin.


Hope this helps,

lf

Building on those ideas, I've been using a wireless, generic and 
chinese remote with the Ds and the Kr, and since I payed some $4 I don't 
mind only one button - all it does is actuate the shutter. Even if I

Used a home made wired switch before - no issues at all. Right now it's

one sold for Canon Xti.

Creativity vs. gear?

2012-08-09 Thread luiz felipe

Igor's words (part):

It has been said many times that abundance of equipment can suppress

the [necessity for] creativity. Or, maybe the opposite is correct:
lack of proper equipments boosts up the creativity.



...snip...


While I would't just say there is something as too much photo gear, the 
step required to expand our photo capabilities sure happens earlier if 
our bag is small. So when I don't have a 500mm tele either I include 
some structure beside the sun or look around to see what's nearby - 
instead of just waiting for the sun go down.


OTOH, even if I carry a large bag there is going to come my way some 
photo I just don't have the right gear to capture, so I'll either 
improvise or tell others about with words. But chances are those moments 
will be less frequent if the bag is big enough. No, mine isn't, never 
was and should never be *large enough*.


Bottom line, I suspect less gear gives creativity more room - but then, 
wich of us don't go exploring each new lens' limits as soon as we get 
one? Buying the Kr did *not* put me in the position of stop improvising 
now and then - gave me new limits to push. Still working at it.

using a reversed wide angle to increase focal lenght of a tele - info needed

2012-07-25 Thread luiz felipe
I remember some article about ultra long telephoto - that's way back, 
in the age of *paper* photo magazines. I've already searched but the 
paper seems to be lost. I also tried the web - lots of articles about 
diy lenses but no one about projecting the image of a tele in an 
inverted wide angle. My memory may be off, but the paper article 
presented various options, from a spotting scope attached to a lens cap 
to the attachment of a takumar 135mm to a spacer, to a reversed 28mm and 
to a slr. The details - that's the problem... no details survived the 
20+ years since I last read the paper.


At the time I had no fixed wide angle - my zoom age - and when I bought 
my next wide lens the idea somehow evaded me. Now I have a spot for some 
1000+ mm lens for once a month usage, not a job so i just cannot add the 
lens to the expense account. Cleaning the 135 Takumar I suddenly 
remember that it's possible to change it into a longer lens.


Memory, anyone? Thanks!!

Self portraiture

2012-06-16 Thread luiz felipe
Use a mirror beside or behind the camera, so you may see what kind of 
face and pose you're making. If you use a large mirror you'll be able to 
see what the camera sees with normal to short tele lenses. Some models 
can use this mirror behind or beside the camera to adjust their posing - 
something useful if you're shooting since yesterday and getting a little 
tired.


Tether the camera, keep the notebook just off the frame - it may get in 
the way of the lights somehow. This should give access to the actual 
photo - keep shooting until you get what you want.


Catch and train an assistant - and tell him to keep silent unless you 
are moving out of the frame. If he says anything about your face, shoot 
-er, fire him and get a replacement.


AF or fixed, avoid wide open lenses or allow creative out of focus 
self-portraits.


The worst about self portraits is you just can't blame the model...

Larry's words:
When there is noone else around to photograph, self portraits can be a 
way to experiment with lighting, however when it comes to actually 
getting decent photos, I keep running into three problems:


1) Framing, I just have to set the camera wide and hope that most of 
what I want is in the frame.


2) Focus, It's a hell of a lot easier using a camera with autofocus, 
but even so the camera keeps focusing perfectly, on the wrong thing.


3) My biggest challenge is that self portraiture is like trying to 
make a silk purse out of a sows ear, or perhaps the whole face.

How much difference does optimizing the aperture make?

2012-06-04 Thread luiz felipe

Larry's ideas:
I was thinking about my quest for sharpness, and was considering 
trying to do some research into what the aperture sweet spot is for 
each lens, and was wondering if anyone had already made a chart of 
them.


Then I wondered how much it really matters.  I've heard a couple of 
stops down from wide open,  anywhere between f/8 and f/16, and a 
couple other rules of thumb.   I do know that on some lenses, 
particularly the FA50/1.4, that stopping it down a couple of stops from 
wide open, makes a huge difference.  And I suspect that if you look on 
an MTF chart, you might be able to easily see the difference between 
f/4 and f/8,  but is there a practical noticeable difference?


There is also the question of sharpness at the critical focus 
distance, and overall sharpness.  That a lens might be sharper at f/4 
than f/16 at the focal distance, but with a lot more depth of field, 
more of the photo will be sharper at f/16, than at f/64.


I'm primarily interested in answers based on personal, practical 
experience, rather than theory.  My hunch is that as long as I'm not 
too close to wide open, or pushing diffraction limits, optimizing 
aperture for sharpness is not the most productive place to spend my 
time and energy.  That I'm generally best optimizing the aperture for 
the picture, and not trying to optimize the aperture for MTF.

Larry, I'd consider both sharpness and DOF when choosing the aperture 
for one particular pic.


Manual focus, f/8 at 2m with the wide part of the 18~55 has given me 
the fastest AF in town. It also has improved sharpness across the frame.


Using the fixed 50s I see a strong diff as I go from wide open to f/5.6 
- but then I often want less focus on the background and accept less 
sharpness.


My old SMC Takumar 135 f/2.5 is soft open and gets very sharp from 5.6 
to 11.


I checked MTF charts / pratical resolution tests of lenses, and did my 
own over the years. Some of my results did go against others, but all my 
lenses are softer wide open than at some other point, both in the tripod 
against some target and in the real world. Knowing what to expect at any 
particular setting is useful, IMHO.


From memory, some lenses got sharp faster - close to wide open - and 
two in particular needed to be closed a lot to behave - an ancient 
Tokina 28-85 and Sigma's 24mm (first version).

Re: Flash Meter experiment

2012-05-31 Thread luiz felipe
Larry, I'd rather use my meters in the incident light mode - assuming 
they had the option. That's probably the the only difference.


I used the Gossen Pro F for a very looong time, and used to bracket 
since local E-6 development had issues. With C41 I hardly used the 
Gossen, but in studio with the Ds and the Xti I had *always* some 
adjustment. If memory serves, the Xti wanted more than half stop more 
light, and the Ds would be ok with a little less than one stop more 
light. So your results do not look odd, even if I don't use grey cards.


Making adjustment according to the image mood and tonal range of the 
subject is sound procedure IMHO - always done that way, limited to the 
kind of film in use. I do want my whites with less detail and more light 
by default - again some adjustment required from the meter reading. I do 
enjoy building the pic if possible.


will check the pics later, underage sidekick is near. :-)

Subject: Flash Meter experiment
Message-ID: 7b7215ab-1ab1-4739-a138-d35ca8180...@red4est.com
Content-Type: text/plain; charset=us-ascii

I did some art nudes with a friend last night using my studio flash
gear.  As an experiment, I pulled out the flash meter and when I'd 
get

my lighting dialed in, I'd take a picture of the flash meter and a
grey card.
As far as I can tell, the way it works is to fire the strobe.  the
f/stop that it reads on the meter is the correct aperture for ASA 50
film.  Point the arrow on the dial at that aperture, then look at 
what

aperture lines up with the ISO, and that's the supposed correct
exposure.

I will say that it never completely blew the exposure, but it was
pretty consistently different from the exposure that I ended up 
using,

about a stop or so under.  In other words plenty of safe headroom for
something really bright in the picture, but not maximizing the SNR on
low key digital photos.  Shooting at ISO 80 on the K-5, I think that 
I

could feel confident that if I used the flash meter, and didn't check
the histogram, I would almost never blow a shot.

I am coming to the conclusion that it is a valuable tool to know how
to use, that there are situations that it can prove invaluable, but
likewise, the histogram is also a valuable tool, and I'd be foolish 
to

rely on the flash meter and ignore the histogram, if the histogram
were available.

For those that would like to check for themselves, fluidr shows the
exif data, so you can see the flash meter reading, and my actual
exposure data.

Photo parties for kids?

2012-04-18 Thread luiz felipe

Larry's ideas, edited:
I wonder how it would work to do a portrait party for kids.  Have 
snacks, toys, games etc for the kids that aren't in front of the 
camera. Do everything possible to make it a fun afternoon, with the 
photography being part of the fun.  Possibly even having costumes and 
props to get kids hamming it up, and maybe even challenge kids off 
camera to make the kids on camera smile and laugh.


It's quite possible that since each kid would be in front of the 
camera for just a short period of time, I could likely even do one of 
these for something like 8-12 kids, and not have to charge lots of 
money per kid.





Larry, I like the idea - but I'm not positive it would work with all 
kids. I know some that require undivided attention and even then have 
problems letting the camera capture them.


I did some ID shots for a model agency - they hired me for a number of 
days, gave their models a time slot like be there 15:45, and I shot some 
8 or 10 each hour. Since they were grouped by age, there was always a 
small group present - one being shot, others in various degress of 
readiness (make-up, clothing, props) and some watching the fun before or 
after the session. The agency had no special focus on kids, so no toys 
were provided.


A small number would freeze completely even in that simple setup and 
require special attention. Some would not succeed at all, and unless 
they had a niche their future would be elsewhere. I had issues with that 
decision, for some that I just didn't photograph well enough delivered 
great results with other photographers. Eventually my position was 
accepted, and those that didn't did well in our studio could bring a set 
of pics within the agency's look for that season.

PUG - Restoring the Missing Galleries

2012-03-20 Thread luiz felipe

Brian's words...

G'day all

A project I've had in mind since taking over as PUG-meister, was to
try to find and restore the first few PUG galleries from 1997/98.

As 2012 is the PUG's 15th anniversary, I decided that now would be a
good time. In any case, it hasn't stopped raining here for weeks so
I've spent a lot more time at the computer than is usual...


...snip... (interesting indeed but snipped just this time)

Thanks indeed, Brian - very nice time travel oportunity, and great 
timing! I'm not really sure, but believe there were at least two months 
without gallery back then, so they should be the sept/ oct/ nov '97. 
Maybe something to do with the move to geocities? I had a copy of the 
PDML traffic during those times, but lost track of it. But memory 
(faulty) tells me there was a period without galleries back then.


Thanks!

photo oppportunities coming soon

2012-03-19 Thread luiz felipe
well, I found what I believe to be an interesting photo opportunity in 
our near future, and felt like giving you guys and gals a heads up. 
Sorry if the news is old or not interesting for some.


Coming march 25 to 27 the new moon is going to join venus and jupiter 
in the afternoon sky. Being very thin at this point, the moon should 
balance nicely with the duo and for those with clear skies some 
interesting views may include Taurus and Orion.


I intend to shoot it, and will start looking for interesting add-ons 
(antennae, structures), since my skies in this part of the year aren't 
usually that clear.


For those interested enough I'd point a link to study those nights (and 
others):
http://heavens-above.com - do choose your location, look for the whole 
sky map and enter date and hour of interest.


For some that may be interested in composing the shot, The 
Photographer's Ephemeris is telling me that those nights the moon will 
be setting between 287 and 292 degrees - you may be able to use a 
compass and look for any interesting structure to place in the frame if 
you feel like. TPE also may help before you leave home - checking in 
advance any fave spots.


Looking forward to those nights,

Aesthetic dilemma: inverted bird

2012-03-12 Thread luiz felipe

Larry´s words to Tim, regarding an aestheticall dilemma:

So it comes down to, are you taking photos for your wife and kids, or
for yourself?

--
Larry Colen LRC at red4est.com (from dos4est)



Now, as long as I agree with Larry´s ideas about the dilemma - no, I´m 
not replaying them all here - I need to point out that fully 
disregarding one´s family ideals on photography may end costing one´s 
dear money in divorce-related matters.


Some possible solutions:
1) go ahead, publish and face destiny;
2) leave at that and face psychologist´s fares later;
3) choose a nom de plume and publish the pic - always a small risk it 
becomes famous and dear family finds out about your double id;
4) find a way to publish under your own name and be paid for it - and 
be sure to spend the exact amount with wife and kids.


Seriously, I´d skip #2 at all cost, probably avoid #3 too - done that 
with words long ago, lousy outcome. If possible, I´d try #4 - but 
publish it I would. I´d rather get problems because I did something, 
than getting angry (and the problems that may come with that feeling) 
because of something I didn´t do. Just my 2c.

Anybody still shooting film?

2012-03-10 Thread luiz felipe

JC´s words...

I have had my Pentax DSLR for 5 years now and only
shot one roll of film since buying it. I am wondering
if anyone is still using 35mm film regularly?

-
J.C.O'Connell
hifisapi at gate.net
-




I still use it, not often. I do use it more often than I scan it - 
there are some 10 rolls waiting my attention rigth now.


Situation #1 - load some roll into my amphibious 35mm (Nikon AW35, 
almost done but still swimproof and clicking).
Situation #2 - load some roll into my disposable 35mm (EOS 500n, bonded 
baseplate, bent strap holders, scratched and gouged elsewhere).
Situation #3 - feel like showing off and load the Mx (twice a year or 
so, and no - the Mx is rather nice).


May stop using soon, since my Fuji supply is almost done and Kodak 
prices here and now are abbusive. Film of choice is any 200/ 400 ISO 
color negative under $7, since E-6 development is something from the 
distant past.

Use a UV filter when playing with steel wool

Larry Colen LRC at red4est.com (from dos4est)



While it looks out of favor, another possible source of lens damage is 
plain, old fireworks.


Even if one's in a zone apparently safe, sudden gusts of wind may land 
more than smoke in lens, eyes or clothing. While the damage presented to 
the lens on the link is rather extreme, even smaller coating damages may 
degrade quality and are easily prevented by a lens filter.


I'd add a lens shade myself - they cut down filter/ front element dirt 
and saltspray for those near the sea, cut down flare, and protect filter 
threads from dings in case something bigger than sparks hit the lens.


...of course if it's big and fast enough there are other issues than 
gear damage.

lighting thoughts/questions

2011-12-24 Thread luiz felipe

Larry's words...
I wonder if anyone has tried simulating a ring light for macro work, 
by putting a studio strobe with umbrella directly behind the camera and 
triggering the camera with a cable release?


In a similar vein, what is the fabric that is used for shoot through 
umbrellas, soft boxes etc?  It seems I could make a really big softbox 
for a lot less than it would cost to buy, if I bought the right fabric, 
plastic or whatever is used for the diffuser.



--
Larry Colen lrc at red4est.com sent from i4est





Larry, I did use a large softbox and a small silver umbrella behind the 
camera some two or three times, but results did not get me smiling - the 
umbrella gave better results for my taste, but more often I'd place the 
light from a side or use the softbox as part of a light tent, not always 
at the top. My tests happened in studio - it's conceivable to get some 
structure to use an umbrella attached to the camera in the field, 
probably even available somewhere.


A friend and teacher built a gadget with a glass panel at 45 deg from 
the camera, that would receive a studio flash and reflect part of the 
blast towards the subject's face. He wanted to do some portraits with a 
fully frontal light, no shadows visible and wanted real power. Results 
were interesting to a point, but the glass at our disposal then (1982-3, 
Brasilian northeast) made him quit. I suggested a hole in front of the 
lens, but he also wanted to get rid of donut shaped reflections on eyes.


As for the clothing/ plastic used on softboxes, I used white plastic, 
vegetable paper and ordinary white synthetic cloth to repair or 
improvise softboxes and light diffusers in the past - color casts were 
the issue since most of the time I'd be using slide film, but a slight 
cast was better than failing to present the pic. It helped when all 
lights used the same solution. The softboxes available here in Br do age 
and develop some color cast sooner or later - so I'll probably have to 
repair mine soon, again.


ps: as the first try to send this msg failed, I looked at the other 
answers and there is some rig to use umbrellas that way.

Pentax MZ-3: is it faster than MZ-5?

2011-09-15 Thread luiz felipe
Just found a MZ-3 offer at acceptable price, and I like the idea of 
keeping a film body around for moments when risk of theft of the KR is 
high - currently a job done by an EOS 500n.


The MZ-3 looks the MZ-5 with DOF preview and a higher top shutter and X 
sync speeds. I'm betting the overall feel and almost all of the results 
will be pretty much the same, but since they came some time apart, maybe 
they present some other diffs. Maybe faster AF, or shorter shutter lag - 
I understand they have diff shutters.


So, any hands-on experience on both cameras? Second to that, is there 
any source of info on shutter lag for the MZ-3 and MZ-5? Any comments on 
the MZ-3? Boz's site shows it to be slightly diff from the MZ-5 in form 
of grip, so maybe it's significantly better than the MZ-5 - I did have 
one MZ-5 for a time so I'm using it as reference.

Nice work. It's clearly extended and there's evidence of structure. It

pfa 50/1.4 sharpness

2011-02-13 Thread Luiz Felipe
Larry, other than the CA apparent on the 1.4, I got the impression that the 
focus is slightly near - the right side of the center rose looks sharper than 
the other. Or you used that border of the rose to focus. It IS softer, there 
are problems if we look to the 2.8 shot at the same time. Still wouldn't stop 
using it whenever I needed to.

I usually close some when I use the m50 1.7 - unless I need it open. Later on 
I'll get the target or a ruler and check my cameras. Didn't do it lately.

pfa 50/1.4 sharpness

2011-02-13 Thread Luiz Felipe
Bob, I did my tests with both m50 flavors I have around, matching the apertures 
from f11 until both were wide open. I targeted a tiled wall, with coins taped 
at center and near corners. Running, between rains. Will repeat one of these 
days with care so I can post results. Mirror used to get things properly 
aligned, don't believe in great errors.

Anyway, my 1.4 acted softer than the 1.7 on matching apertures. The 1.4 is 
older, had some fungi removed from front and rear elements but there are no 
stains in the coating - that may be the problem anyway. But I got the idea that 
the 1.7 is a little sharper - at least, mine is. There some diff in exposure - 
I was using manual speeds, metered from the Gossen often but not for every 
shot. Next time I'll get it proper.

Luiz Felipe
luiz.felipe at techmit.com.br
http://www.techmit.com.br/luizfelipe

Bob's words:
It may be just me, but I'd compare the f/1.7 lens with the f/1.4 *AT* f/1.7.

Reason? If they're both about the same at f/1.7, then the f/1.4 lens is just
as good as the f/1.7 for all purposes you would have used the f/1.7. Bonus:
a little more aperture available to control DOF with the 1.4.

Sensor Cleaning

2011-02-11 Thread Luiz Felipe
I had some dust issues with the Ds, and eventually bought the Pentax Q-tip to 
settle matters. Worked like good magic, no hangovers nor headaches after the 
performance.

Curiously, some net addresses mention a similar product from Canon, said to be 
sold only in JP - and no Pentax cleaning tool.

Shooting wide open helps a lot - I'm positive both cameras have some spots that 
just don't show at the large apertures I've been using lately. Some other day 
I'll get to clean them.

Ken's words:
I've had 3 Pentax digital SLRS and sensor cleaning is a very seldom needed 
thing with my cameras - I go out of my way to keep dirt out and I've shot in 
freezing snow storms, pouring rain and high winds in the desert.
When changing lenses,I keep the camera body opening facing down and am as 
quick as I can be in reattaching the lens.

pfa 50/1.4 sharpness

2011-02-11 Thread Luiz Felipe
Larry, you and Paul got me thinking about a test with Yvon's AF target - just 
to make sure there is no micro shift made evident by the 1.4 aperture. I 
understand the 1.4 lenses got slightly worse results wide open than the 1.7, 
and my rather crude tests point in the same direction. If you get to test it, 
post the results, ok?

Of course I'd still go for the slightly OOF pic, as opposed to the words 
describing the UFO.

 more adjustment than any of my DA or DA* lenses.

I ran versions of the test with both autofocus, and manual focus with the 
katzeye, and got very similar results.

Some of it was CA.  Oddly, to me, this lens doesn't seem to be in the 
lightroom lens correction database.

enablement: new camera in town

2011-01-27 Thread Luiz Felipe
Just received my new Kr, bought in the US with the great help of Larry Colen. 
Really interesting camera, that will be completely tested (again) in the next 
few days.

First impressions:

Smaller than I expected, feels great in my hands, like the weight and the feel. 
Somehow the Ds feels better built - power and DOF preview switch in particular, 
but other details as well.

Slightly smaller viewfinder than my Ds', something I consider important. Bright 
image, hope to get used to it soon.

Not so great control set IMHO - in order to get DOF preview I had to customize 
the green button, still wondering at the consequences. 

The very big LCD really makes the difference, but for my taste it's a bit of a 
nuisance getting it on while I have the camera at eye level, even when I change 
camera mode. Will try other settings soon - maybe this will not remain a 
problem. Of course live view is a very useful tool.

Louder than the Ds - still a nice sound, and I'm not into stealth photo. Can't 
object to the vibration/ slap of shutter and mirror so far, more tests to 
perform.

AF feels faster than the Ds, even in light levels that won't trigger the AF 
light in the Kr. Of course those other testers had it right... :-) AF in video 
is so-so for the first moment - not good but useful enough. Video quality looks 
very, very good - without proper operator training.

First results look very ok - won't get posted as I didn't get a proper model 
release. Second batch should be made soon, with greater care and control - and 
posted. I really don't expect to get better results from a very capable but 
much older Ds. Unless we count pics lost due my aging eyes vs. the smaller 
finder. 

Something I already knew from Larry's tests, but had to see for myself: the 
camera at 12600 beats the Ds at 3200... and I already felt the Ds as very 
interesting at 3200. Really impressive... 

Two particular points of interest - the flash is behaving as it should, with no 
signs of failure, and the rear wheel looks happy to change the camera's 
settings without problems. Looks like the problems solved themselves - bad 
contacts probably. 

Again, my Thanks (capital) to mr. Colen for the purchase, test and first 
evaluation of the Kr. I'd be still using the Ds without his help. Thanks!!!

Vivitar 2600-D trigger voltage?

2011-01-10 Thread Luiz Felipe
Glad you grabbed the gear, Larry!

IMHO there is NO substitute for a real test, with a voltmeter, even if the 
flash is listed as safe - there is word written out there about diff versions 
of flashes with completely different voltages AND the same model number.

Just get a voltmeter across the contacts, and watch voltage levels from the 
moment you turn the flash on to the recharge after you trigger it. An analog 
voltmeter, while not as easy to read, may be helpful to understand quick 
voltage rises that will not register so well in a digital voltmeter.

My old 285hv lies on the danger zone at 7.5 volts - assuming the safe is 6 
volts.

 The flash may be of interest and use, but I can't find if the trigger voltage

I'd usually check on botzilla. The Vivitar 2600 is listed as not safe,

What to charge for a friend's wedding

2011-01-09 Thread Luiz Felipe
Quite a number of sound ideas and advices so far, so I might only add: beware 
of Murphy. Of course, you are welcome to keep reading the rest.

Around here a wedding photo album offers great cash values AND still greater 
responsibility. Fail to do the job and you have a life-long enemy squad. 
Failure includes not meeting expected styles and key shots... do ask them 
exactly what they want, with example if possible. If it's not in your grasp 
(need extra hands, special gear, not a style you are ok with), do tell them. 

- trusted, adequate gear and suitable backup, including batteries and cards - 
rented gear may have lower batt life than expected, not to mention other 
issues. Proving the rented gear was the problem will not be enough...

- helping hands are welcome, but asking for the 16-50 and getting the 15mm is a 
problem, not to mention the possible dropping of stuff while both are looking 
at the bride's best friend. A friend of mine almost lost his Xti when a helping 
hand tried to insert the second card inverted...

As long as I love helping friends and taking photos, I'm too rusty for a proper 
wedding job these days, and even if the Kr came home today I'd need to train 
myself to its layout. Later I'd probably be at ease with the gear, so I would 
probably accept, as long as the expected kind of photo is within my ability and 
gear - and since I don't know the ceremony well enough I'd insist on being 
present at any rehersals, discussing the photo ops with the couple. Wouldn't 
charge at all, accepting only high value, third party costs. 

PLS beware of Murphy - he managed to put my car on fire on the way to a job, 
causing me to arrive at the church covered in white powder, a few seconds 
before the bride - who accepted to take a third round-the-square car ride while 
I shook the worst of the powder from me and my bag. No adittional events, 
couple smiling during and after getting the prints, but I decided to call a 
break after that, sold the Hasselblad rather cheap and burned the clothing - 
not accepting the risk of poisoning anyone by throwing it off. Did rebuild the 
car - was a small fire and I carry two extinguishers.

Well, I'd hope they have much in common. Still, there should be some diff at 
sensor level, or DXOMARK wouldn't give them diff rankings (82 vs. 72).

I do agree with your point, Paul. The K-5 advantage will most probably be 
noticed only in more extreme situations. Still, I suspect there will some 
moments where it will be decisive. Not that I expect to be in one of those 
situations anytime soon... :-(

I don't think the K-5 is noticeably better in terms of noise. The advantages 
lie elsewhere, probably in exposure accuracy, autofocus, resolution, 
weatherproofing, and perhaps dynamic range. I don't think you'll  see much 
difference in a comparison of web-sized images.

Is a P5 worth anything?

2011-01-09 Thread Luiz Felipe
well, the P5 is quite an interesting camera with the drawbacks listed by Brian 
below. The 50mm in question looks like either a K or M 50mm, and the price is 
rather interesting - a clean one in BR goes somewhere between $70 and $130.

I'd rather an A/ FA 50mm myself, actually. I'm quite happy with my m50 1.7, but 
sometimes being able to work in auto aperture would be very interesting.

Well, the 50 1.7 is certainly worth $30, if it's in good nick.

I liked the P5 (P50 here).  It was my workhorse camera for quite a few
years in the 1980s/90s.  I always liked the look and feel of it. It had
its limitations (no manual setting of ISO; no TTL flash; no manual
shutter speed, so without batteries it was cactus) but, for what I was
doing with it, those things weren't important to me.  I still have it.

Pentax K-r and QC

2011-01-07 Thread Luiz Felipe
Well, that is a problem indeed, in particular when we remember a small but 
noticeable number of K-5's came with sensor issues, and there is an also small 
but noticeable number of SDM lense failing too soon.

I don't expect a 100% rate of success from any kind of product, and I'd be 
quite happy to learn my problem is one in a very large number of successful 
sales - but if Larry wouldn't be checking the camera, I'd be discovering the 
problem only here in BR, and would face a much, much greater cost to return it. 
Not to mention the taxes involved - as the replacement camera would just be 
taxed too.

The Kr seems a very interesting camera indeed... 

Larry my friend, thank you very very much!!! Again!!!

Luiz Felipe
luiz.felipe at techmit.com.br
http://www.techmit.com.br/luizfelipe

starting copy
Luiz's K-r arrived today.  Once the batteries charged I got to play with it a 
bit.  The biggest annoyance was not being able to turn off the info screen, and 
not having how to do it easily findable in the manual. (camera menu 4, memory, 
save picture display). In every way it is an improvement on the K-x.  I still 
want a K-5, but if I could do so for a couple hundred dollars, I'd be very 
tempted to trade my K-x in for one. And you know how much I love my K-x.  The 
frame rate on autobracketing seems to be 2-3 times as fast.  Autofocus 
indicators were sorely missed. I haven't done side by sides to compare 12,800 
on the K-r with 6,400 on the K-x, but I wouldn't be surprised if they were 
pretty close. Autofocus seems a bit faster, and the autofocus light is a 
welcome help.

However, this unit is a sad example of the state of Pentax QC.  The thumbwheel 
is a bit flakey.  Most of the time, when it clicks, the appropriate value 
changes one click but it seems to miss clicks now and then. Sometimes one in 
10, sometimes two or three in a row.

Then when I was trying to take a photo of something on the covered bridge that 
was back lit, I tried to use the pop up flash.  Nada. I could get it to pop up, 
on auto, on manual, when it's dark enough to need a half second exposure, but 
still, no flash.  Two failures on one camera is beyond acceptable. I will 
concede the possibility that they could both be caused by the same loose 
connector, or faulty component, but that's a possibility, not a probability.

help needed: Pentax stores in Portugal or Andorra

Luiz,

I bough my Mz-5n in Andorra around 8-9 years ago and the prices were quite 
interesting at that time. However, I have the understanding that it is not that 
interesting after the Euro, although there are still some deals.
An example (I guess you'll be able to read Spanish) from the main Spanish 
Pentax 
forum:
http://www.pentaxeros.com/forum/index.php?topic=35370.0

They even have a shop that is a good representation of the best prices that you 
can find in Spain for new Pentax equipment:
http://www.tiendapentaxeros.com/

From what I see online and in magazines, the prices in France are higher than 
in 
Spain (and Andorra, of course). I don't know about Portugal though (I live in 
the opposite side of the peninsula), but I don't think that is is specially 
cheap (the importer is the Spanish one, Reflecta).

I'll ask some colleagues for shops in Andorra and let you know off-list. If you 
are going to visit Barcelona, let me know and I'll be happy to inform you about 
the best shops for Pentax

help needed: Pentax stores in Portugal or Andorra

2010-12-13 Thread Luiz Felipe
Well, as I said above I'm needing addresses of camera stores in Andorra 
(Portugal and Spain as secondary options - most welcome but would need some 
extra time). The catch - those stores should offer Pentax K-r... any ideas?

I'd be traveling really fast around the area, but my schedule calls for a lazy 
day (for me) in Andorra. I'll be packing my group towards BR from Lisboa but my 
last day in europe will be spent signing papers and fighting bureaucrats - 
little time to buy gear.

As part 2 of the question, is there any difference between camera prices 
between Portugal/ Spain/ France/ Andorra? Back in 1982 I bought my Lx in 
Andorra at a very interesting price - lower than some New York stores 
advertised. Is there any difference between countries in the area?

back in the world of film (sort of) with my MX

2010-07-10 Thread Luiz Felipe
Christine, the Mx is very close to a DSLR killer - when it comes to size and 
viewfinder. Even the full format DSLRs have problems matching the Mx finder, 
due to light losses in the mirror to allow for AF and fancy metering. True, a 
modern focusing screen can shine here, but the moment you give the same upgrade 
the Mx the results from the oldie shoud improve too...

Never got a neutral copy from those c41 bw films unless I sent them to bw lab 
for printing, but the quick return from a nearby minilab got me out of trouble 
more than once - getting me an early ok from a client so I would move to the 
next studio setup, prints to be delivered later in proper.

Very interesting pic! You got me thinking about carriyng the Mx more often. But 
that also means lab developing, film scanning... :-/ OTOH, every pic is 
available for a second high res scanning if I manage to catch anything of 
interest... next week I'll give it a try.

Godfrey, Adam;

Really a subjective matter - not science, so diff opinions are 100% ok :-)

No hands (or eye) experience with the A900. Quick tries with Canon and Nikon 
finders, APS and FF, all darker than Lx  Mx. No fancy focusing screens. Lx 
wins (for me) due to adjust - I'm shortsighted and the Mx lacks adjustment. But 
both are outstanding for me. I did choose the Ds over the Dl because it's 
finder is slightly better - big diff for me, spoiled by ages of Lx and Mx. Used 
Canon's F1n for years, didn't enjoy its finder that much. Use often Canon's 
XTi, hate its finder. Again, my feelings on the matter. :-)

. 5) When I'm shooting in low light, even if I'm just playing around, if 
my shutter speed is under 1/30 of a second, I really do need to use at least a 
monopod.  Even if it looks OK on the camera display, I'm going to lose most of 
the shots to camera motion if I hand hold the camera.

. Do you use any kind of conscious breathing technique, i.e. do you

. Implicitly, if not explicitly.

.I guess I just have to learn not to forget my monopod =)

Carry a loop of cord in your bag, long enough to step onto one end and pull 
lightly at the other to keep the camera at eye level. That is, assuming the 
place you're shooting would allow (no crowds, no people moving around fast). 
Keep some soft clothing or a neoprene mouse pad ready to shield the camera from 
rough surfaces you'll be leaning on. Practice Vipassana Meditation or some Yoga 
of your choice. Enjoy while you're young - it's being a long time since I was 
able to even try handholding cameras near 1/30 sec...

Of course, do keep the tripod/ monopod/ walking stick nearby...

As for pushing the ISO, I'm almost always at the extremes - the Ds spends more 
time at 200 and 3200. Noise Ninja helps.

I have a fair understanding of how easy is to lose attention for a moment and 
come close to disaster. 

As much as I believe every help is welcome in safety matters, I'm positive 
those warning devices are going to be questioned in court as soon as installed. 
Translating the matter to a diff world, I've seen those who blame the gun 
safety that failed, instead of admitting they had their fingers at the wrong 
place - pressing the trigger when they didn't mean to shoot. No, that should 
not prevent their release.

Once a diver, I'm familiar with many cases where scuba gear manufacturers were 
sued and even decided to settle out of court, cases where the problems were 
caused by fatal mistakes of  the deceased or crippled divers. Sadly there are 
lots that just blame others for their mistakes. Not to mention those that will 
seek profit at every possible situation.

I'm for the warning systems. But there is NO substitute for full and complete 
attention in those moments. I got the habit of talking endlessly to my son 
every time he's in the car with me - after the day I skipped the way to the 
school, and only noticed my mistake when I arrived at my workplace with him. 
Not a risky situation as it happened, but scared me silly. That should never 
have happened. Soon he was helping me to choose the way, look for parking 
places - a perfect co-pilot, rather than a sleepy passenger. It's more fun, 
also.

A very well placed article, and in my prejudiced point of view covered that sad 
situation very well indeed.

Good point, might be an alternative to factory-issued protective devices. I 
still think the absent minded may forget to keep d...@mnd batteries fresh, 
tho. Manage to build such with some kind of movement- charging device and it'll 
be almost foolproof...

A factory-issued item would be part of the periodic maintenance schedule, and 
probably best to the function. But more sue-able too.

OT: Kids are Dying in Cars

2010-05-29 Thread Luiz Felipe
.Larry's own words...
.I certainly don't doubt that for the parent of the child, no price would be to 
high to save the kid.  But my complaint is with trying to equip every car with 
that solution. .Should every person in the US pay a dollar to maybe save half a 
dozen babies, when that same money could probably save hundreds if spent 
elsewhere?
.
.My inclination would be a bluetooth device that you could clip to the baby 
seat, and a program that would run on your cell phone, or a dedicated device) 
that would .alert when the sensor got out of range.  Likewise, it could alert 
if the temperature got too high, or too low.

Larry, I kind of agree on the math - not placing a value on life but wishing to 
make more of the resources. But I suspect bringing the number of those 
tragedies to zero over some time span would mean some financial savings as 
well. I'd try it just for the life loss, but there is some money spent on those 
cases that would be saved otherwise. I do suspect those factory-installed 
devices would increase car prices by more than 10 dollars...

Maybe between you and Ecke some chinese venture may be developed to market 
those aftermarket devices. I'd probably buy one myself, to interface it into 
the nano-itx videorecorder and mp3 player I'm trying to build. Ecke, if you go 
for the movement generator there is a whole green effect - very interesting 
these days. :-)

Cleaning Sensors

2010-05-17 Thread Luiz Felipe
I have used the Pentax cleaning kit twice in the Ds - there is some stuff that 
just can't be blown away, and it seems to arrive at the sensor a day before 
some important shot.

A good blower is very important indeed, but there is no way a blower carried 
loose in the bag would remain clean long, and even one left open in a shelve is 
prone to blow some more dust into the sensor. I keep a small in the bag, 
zipped, and a big one at home, also zipped, right next to the cleaning kit.

Interesting ideas, both - never used anything like that.

Most of the time my monopod is either in the trunk or my hands, when it doubles 
as walking stick in rough terrain. Did attach the older one to my bag, but 
found it rather clumsy and later bought a shoulder bag. But as soon as I enter 
the area I'm shooting, out comes the walking stick - er, monopod. I do use it 
to steady the camera, now and then.

Tripods that fit in carry on

2010-05-03 Thread Luiz Felipe
Godfrey's own words...
.I've carried-on my Feisol CT3442 Tournament tripod several times.
.Folded and in its case, with Acratech head, they're 19x5.5 and weigh
.4.2 lbs. I don't put It in the carry-on bag although it can fit if I
.take it out of its case.

Last time I checked one would be allowed the carry on bag and one extra piece 
such as camera bag or lady purse. don't know if we would be allowed a tripod 
bag and a carry on, the camera being inside the carry on and the tripod inside 
the longer shoulder bag. I carried my old Vivitar in its bag and my camera bag 
into a plane (2001) without problems, but the next time some suspicious mind 
insisted on opening the checked tripod bag in my presence, suspecting of gun 
parts (2001 again). Last year I had no tripod issues - left it home and 
regretted every second.

I suspect the tripod may be objected as a threat, no matter how you fit into a 
proper bag. That's one issue I'd follow carefully.

A Crazy Idea

2010-04-06 Thread Luiz Felipe
Paul wrote, and I read...

..I never used a zoom for my first 30 years of photography. Mainly because they 
just wren't very good. 
..I was exclusively a prime shooter. But today's zooms are good enough that I 
rarely use a prime.
..With the DA 12-24, the DA* 16-50, the DA* 50-135 and the DA* 60-250, I get a 
huge range of focal 
..length options with performance and speed that is the equal of most primes. 
Hell, nearly all primes. 
..Primes were once a far superior choice, but no more.
..Paul


From 1976 to 1982 I had only primes - and for the first year only the 50mm 
1.4. Before that I had
35, 50, 90 and 135mm lenses (Dad's). That made me able to move around instead 
of zooming the
world to my desires.

After '82 I used zooms as possible. Including Pentax's 35~70 2.8~3.5, that gave 
some competitors 
headaches in the Lx+ AF280t combo since I could move, zoom and TTL in a time 
many around me 
still used fixed 35mm and manual flashes to shoot events. At the time zooms 
were well below in quality 
- but then who wanted that sharpness in newspapers? Still kept a wide, 50mm and 
a tele, fixed, as fast 
as I could afford. Some got fungus.

Moving up to product and fashion I got back to primes - exception being fashion 
events where models 
were falling everywhere :-) Zooms still left very much to desire. Also moved to 
6x7 and 4x5 - yes, with
fixed focal length lenses. Gave up aperture and mobility, sharpness was my goal 
in that space-time.

Got back to zooms to avoid changing lenses in dusty, dirty places - and no need 
for that super sharpness 
again since the environment and intended use of the photos were lousy and small 
pics, respectively. 
Cheap and lightweight are beautiful when gear may be damaged, stolen or carried 
over long stretches of
impenetrable country.

I'd still choose primes today - assuming the ca$$$h availability - as I still 
object to barrel distortion in wide 
and would rather faster lenses as possible... some primes still offer an edge 
here. 

That said, and taking money as main motive, I'm living with 50 (3 diff 
flavors), 135 and 200mm primes 
- and  the 18~55, 28~70, 28~200 and 80~320. And when I think about strong winds 
blowing sand and
salt spray I still think about zooms and cheap cameras. Of course, I'm not a 
working pro lately... :-(

Final (for now) idea: giving the 18~55 a formal try as almost full format 
lens, in particular at the 28 to
24mm focal range - on a simple test soon as I got the Ds, I noticed it's almost 
covering the viewfinder,
and presents very low barrel distortion as compared to both the 28~70 f4 and 
Tamron's older 28~200mm
zooms. Since I frame within the viewfinder, as long as what I framed is there 
there will be only one issue -
actual image quality. And that shall be measured against intended use, as I 
always have done.

Hey, this thread is named crazy idea, isn't it???

Person sized light box?

2010-04-06 Thread Luiz Felipe
Larry's words:
..Nope.
..
..There were some interesting aspects to the lighting from last night that 
..I think it could be fun to explore.  I was wondering if anyone else had 
..already done something like that, how it worked and how they 
..accomplished it.
..
..I don't want totally flat lighting, but large, directional, diffuse 
..lighting.

Well, I didn't do it - back in time I'd just use papel vegetal (vegetable 
paper is the meaning, 
it's how we call around here a highly translucent paper with very good heat 
tolerance) across 
light tripods or otherwise built frames. Bigger than our 1.5 meter hazy, way 
smaller than you
need. But I'd give it a try either hanging from the ceiling or building a frame 
of sorts - made 
frames with PVC piping, for a friend's studio, and they are lightweight and 
simple to assemble.

Fabrics or plastics will offer you various degrees of diffusion. Of course, 
heavy materials would
require strong frames.

Of course some tent may be readily available... and there are high end 
materials, and some
of us love wood... or you may use aluminum tubing and build a fully modular 
system... 

Serious, a number of frames that may be covered with translucent or reflective 
materials is
very helpful in a studio/ location shot. If you don't find near you or 
mail-available, just build it.

Don't forget to post the pics ;-)

A Crazy Idea

2010-04-04 Thread Luiz Felipe
larry's msg read, among other considerations,

..I know that when I spend a lot of time photographing with just a  
..single prime lens I learn a lot more than when I use a zoom, or even  
..swap lenses on a whim.  Spending a few weeks shooting almost entirely  
..with the 20mm taught me a lot about selection of focal length, and it  
..changed the way I use zoom lenses.


looong ago, but already into the zoom age, I mounted a small photo class. one 
of the tools was black adhesive tape - on the practical lessons I'd tape my 
victim's zoom at odd lengths to make them move instead of zoom. further down 
the classes they became stuck again, this time in focus. lots of laughter, but 
some useful concepts too. over the time I do change my pet focal length - I'm 
sort of rediscovering the longish normal lately, either with film or digital.

on a side note, sorry about my absence - assuming it was noticed :-) - things 
happen.

FA 28-70 F4 on digital?

2010-02-02 Thread Luiz Felipe
I have one of those, and have used it quite a while with the MX - until I got a 
DS with 18~55 last year. It's still in the 35mm bag, and scheduled to a series 
of trips to a rough area of the state.

Image quality is rather good, much better than Canon's 28~80, apart from a 
serious barrel distortion at its wide setting - which the DS reports as 31mm, 
not 28mm. Major drawback: the front element rotates as focus, so polarizers and 
graduated filters become a major pain. Much is written about the rear element 
separation, but since it's a fairly cheap lens in the US I'd buy it for full 
frame uses under the light carry gear cat. My sample has endured lots of 
abuse so far. Light falloff and edge resolution are no problem with APS 
sensors. Sadly the distortion remains there, a problem for me.

lf

original message follows:
I had one and used it for quite some time on the old *ist D and loved 
the results.  I've got a few nice scenics that I shot with it.  One 
thing I miss about Pentax DSLRs is that the low-end zooms like the FA 
28-70/4 are far superior to the low-end glass available from Canon.

OT - CinePaint and Pentax Photo 3.61 under Linux, work in progress

2010-01-25 Thread Luiz Felipe
Hi Graydon, thanks for the comments - and sorry for the delay, things happen... 
:-)

Just found the damned package, downloaded and all is working... so far.  Just 
made a try with Camera Raw (can't remember the version, came with my CS2) in a 
night shot and I'd keep UFRAW no matter what. CinePaint is not CS2 - I can't 
find my way around some tasks - but for anything that doesn't require extensive 
healing or editing it's going to be used. Right now I'm trying a quick fix for 
CS2 under Wine 1.0 (alt key shortcuts), since I have some heads to move around 
older pics and I'm under 10 hours of use of CinePaint and still have a long way 
to learn. Time, again... and all that while the kids come to ask anything from 
a kiss to why can't we just go back to the beach to see it by night... and get 
more ice cream :-)

The 16 bit depth stays as long as possible - same as loseless compression. Any 
losses come as final step, if needed - both in image and sound. I don't print 
at home - so far. But I'd keep as much detail in the pic for as long as 
possible because once it's gone, it's gone. Tomorrow I may need it, who knows?

Link to the missing link: 
http://security.ubuntu.com/ubuntu/pool/main/o/openexr/libopenexr2ldbl_1.2.2-4.4ubuntu1.1_i386.deb

Amazing as may seem, my previous searches didn't get this particular result. 
Typing errors? The correct search string was on my cache, and the other 
(followed) inks appear in the google results... Gremlins - it's NOT old age... 
But Synaptic and Apt-Get missed the target too.

On Fri, Jan 22, 2010 at 04:16:40AM -0200, Luiz Felipe scripsit:
 Cinepaint never worked for me. Last week I came across a piece of info
 that allowed me get it working, without crashes so far. It's still a
 work in progress, since some software dependencies aren't met under
 Ubuntu no matter what - but I just can't try other distros right now,
 no more tests for the moment. I'm wondering if any of you have managed
 to work from SD card to print in Linux. And how.

ufraw for raw processing, cinepaint for anything (like detailed colour
balance fiddling) ufraw doesn't do if you need 16bit.  I mount the SD
cards directly (just sticking them in a USB reader should do that) and
copy the files off them into a directory.

If you're using apt-get and cinepaint is a ubuntu package you should
certainly get all of the dependencies.  (As a general rule, if it's not
a package, you don't use it. If you are not utterly certain what using
force will do, don't do it.  If you break either rule, there will be
learning experiences.)

I will note that I can't readily see the difference between 16bit and
8bit colour in print output; I suspect I would need a good dedicated
photo printer for that.  (I have a Xerox 8550 solid ink printer.  I
really like it, and Xerox claims full Pantone capability, but it's not a
photo printer.)  If you've got one, I'd be making sure that you can
print to it first.

If it's just going to jpeg *anyway*, ufraw + gimp works fine.

 Both systems are fully up-to-date - an issue since after the forced
 CinePaint install all package managers refuse to work proper unless I

 so far (libopenexr2ldbl (=1.2.2)).

OK, delete -- using the package manager -- cinepaint.

libopenexr2ldbl is a Ubuntu package; what response do you get when you
try to install just it?

Night repairs

2010-01-21 Thread Luiz Felipe
Very interesting set, Larry. Make mine the first, small margin - the others 
aren't so behind for my taste.

I'd get a voltmeter on the setup, to check if the Van is keeping up with the 
inverter at idle. and do watch out for signs of excessive heating. You probably 
don't want that pair of batteries to deplete past the point where they turn the 
van back on...

Thanks.

For what it's worth, I'm now running my1100W inverter off the  
deepcycle battery, jumpered to my van battery, as my van idles in the  
driveway.

OT - CinePaint and Pentax Photo 3.61 under Linux, work in progress

2010-01-21 Thread Luiz Felipe
Well, I did manage to get the Pentax stuff (version 3.61) running under Xubuntu 
Linux and Wine some time ago, but had some issues with the GIMP photo software 
since it's 8-bits (color depth) only. As I still had Photoshop under Windows XP 
in another machine, there was no big problem - my notebook's monitor isn't that 
good anyway. Sadly the XP machine acquired a terminal moisture-related ilness, 
and is scheduled to be shot one of these days at our local target range - so 
I'm to fully edit my photos on the Linux notebook. 

Cinepaint never worked for me. Last week I came across a piece of info that 
allowed me get it working, without crashes so far. It's still a work in 
progress, since some software dependencies aren't met under Ubuntu no matter 
what - but I just can't try other distros right now, no more tests for the 
moment. I'm wondering if any of you have managed to work from SD card to print 
in Linux. And how.

My current setup (two disks, one system older, one new):
Xubuntu Linux 9.04 + Wine (1.0) + Pentax Photo Lab and Browser (3.61, installed 
from the Pentax site download) + UFRAW (0.15-1 build 1) + Gimp (2.6.6) + 
Cinepaint (0.22-3 from the debs by Aedan Kelly - only setup that did work so 
far). I did install Nautilus (1:2.26.2) since it's able to display the PEFs as 
icons too, assuming UFRAW is installed.

The second hard drive is a fresh Xubuntu 9.10 install, same programs. 
Noticeably faster than the other, but since the hard drives are diff I can't 
really say it's the new distro. 

Both systems are fully up-to-date - an issue since after the forced CinePaint 
install all package managers refuse to work proper unless I take down ditto 
CinePaint as the failed depency is impossible to meet so far (libopenexr2ldbl 
(=1.2.2)).

After all that, I'm out of ideas - and time. If one or more of you have more 
info, I'd love to read about.

Aedan Kelly's efforts on CinePaint may be found at http://sidux.net/etorix/ - 
for those interested in trying. For any interested, my road to (x)ubuntu 
started with an ancient BR-customized distro, Debian-based called Kurumin, now 
extinct. After the original brain quit, a last effort to keep Kurumin kicking 
was a Kubuntu remaster. Wich prompted me to include those among the distros I 
was testing at the time. So far it's ok - since 2008 I chose Xubuntu - which I 
regard as just a little faster and smaller than its cousins.

TIA, good light, great photos - to you all.

Subject: Fw: K20D - Hot pixel ?

2010-01-20 Thread Luiz Felipe
Ken, bad news indeed. I'd second Ecke's idea - the K-x is rather close in $$ 
and you'd get the best high ISO performance this side of the k-mount frontier.

I'm not suggesting the K-x would be THE replacement for the K20, but all the 
same, it's not that bad. Paying $400 for the repair seems a tough option.

Good luck.

back- mostly in lurking mode, intermitent web access

2010-01-17 Thread Luiz Felipe
First, thanks for the wishes and tips, back when I unsubscribed for my trip to 
MouseWorld - I seriously misjudged my free time, and ended up with far less 
than I expected... no parties :-( On the bright side, despite a chilly start 
and a series of inspired moves by Delta Air and the worst hotel at 
International Drive, my yells were heard only in Rockin' Roller Coaster (seems 
faster yet, and maybe it is since my bag was lighter than usual and still had 
to grasp it hard), Tower of Terror (four falls, better rythm, forget about 
using heavy cameras - you'll get hurt) and other select rides... did rise my 
voice at the hotel some, but that is what one gets for staying out of Disney/ 
Universal resorts.

Thanks to Pat, I did return home with an outstanding FAJ 80~320 copy, 
co-responsible for some wildlife shots - I did manage to click the DS over a 
thousand times, looks like I'll keep 20 or so :-) Thanks to Larry, the DS 
should get a much needed clean-up one of these days. Buying eneloops remained 
on the list, tho... maybe next time, hopefully soon. Same for diving, driving 
down the Keys and some other things. That's ok - one should always keep the 
to-do list populated.

Being without a proper internet access, I tried to keep away from PDML - away 
being reading the archives two or three days each week - but this IS 
addictive... so I'm back, digest mode for a while... pls don't expect fast 
answers. I'm also trying to figure out what to subscribe for PUG and The 
Book... and trying to keep the photos organized. Should have bought that 
d...@mn3d hard drive...

Came home to face some new challenges - I never had so little concentration to 
computer issues since I started fixing my friends' machines some 15 years ago, 
so looks like they're going out of my life. Being 48, the number of ops is not 
that great, too. Most of this town's Disney Advisors is under 35... I knew 
there was a bet before my trip that I'd need a medic in the US - only couldn't 
place my money on it, pity. Going into the Model Studio is pointless, since 
there is always a newbie group taking pics for free to enter the market... as I 
hear from the veterans of today, which I remember as newbies from ten years 
ago... and yes, I told them at the time they would understand better what was 
the problem of taking pics for free for a start... we'll see. I know for sure 
I'm not stopping photography anytime soon.

I'm back :-D

Re: Adobe software status

2009-11-20 Thread Luiz Felipe
Larry, I'd favor the plain Photoshop CS4 for linux - AKA Photoshop CS4 
for Windows, installed by means of a special environ called Wine, under 
Linux. If need be, I'll keep using Windows a little longer.


Photoshop CS4 win32, for me. If available, of course. I can continue 
using CS2 with little or no problem.


Did I thank you lately??? TKS!!! :-)

Re: adobe software update

2009-11-17 Thread Luiz Felipe
TKS Larry, I don't think that would be necessary. I'll be staying a few 
days in FL early december, and the program should return home with me 
properly installed in the notebook, media among the ones burned during 
the trip or even inside the drive.


I wouldn't mind a reasonable tax myself. The current layout was devised 
to make short of impossible bringing to BR things that would endanger 
local industries - the original list left almost nothing behind. There 
is a legal nightmare about that issue - since cameras are fundamental to 
my work as photographer and there are no local built options I should be 
allowed to import my tools with a very low taxation. Theorethically...

CS4 media +license.

It makes little sense shipping it to BR since depending on how the

price+shipping.


If it comes down to it, I could send it to you on a ripped DVD labeled

ot but not that much: trip to FL in december

2009-11-17 Thread Luiz Felipe

My long delayed trip to Mouseworld is scheduled, again. It's kind of
work, since I'll be driving a small group around the parks, visiting
hotels and attending to meetings. In short, my time is not exactly mine
:-/... but I'll be doing some things I enjoy very much, and hopefully my
charges will be able to fend for themselves during shopping days and
nights :-))

So far I'll be in Orlando from december 5th to 14th, and possibly a
little longer - at the expense of two days in Atlanta.

I would be very glad if some time and place within that window was spent
in PDML style... so PDML members from Orlando and neighbor cities, pls
get in touch. This email address will remain in use during the trip -
but I'll probably unsubscribe from the list a few days earlier.
