comparison pictures between it and the A24/2.8 demonstrated the  
A24/2.8 to be a much better performer at nearly all apertures.


I don't know the K24/2.8. If it is the same optically as the A24/2.8,  
I'd stick with that or go for the FA20-35/4 AL if you want autofocus

Not necessarily. For instance, the DA40/2.8 has been shown to fully

DA16-45 and DA18-55 can be used with good results on 24x36mm as long

More significant is that the DA series lenses have no aperture ring

the aperture from the body.


I tested the DA14 on the MX body. It vignettes quite a bit but still

The DS' auto-power-off function is adjustable using the "Set-up"

almost always leave the camera in my bag with the main power switch

take a shot, you get into the habit of touching the shutter release,  
which switches it back on and activates the metering system.


The metering system has its own timer as well. It is adjustable  
separately from the auto-power-off function: in the "Custom Settings"  
menu, you use the Meter Operating Time function to set it to 10, 3,  
or 30 seconds (10 seconds is the default). This setting will adjust  
how long the metering system display stays active after the shutter  
release is pressed half-way and let go, without releasing the

turn off in about 3 seconds. (The meter display will also stay active  
for as long as you hold the shutter release pressed half-way.) I  
always leave my cameras set to 30 seconds for this function.


The DS power up and meter activate when you touch the shutter release

I am not sure if exposure correction setting is a "user setting",

Can be quite painful when shooting in hurry when lighting requires  
some EV correction. Two times I needed to change batteries in

Interesting, I'd not noticed that before. Thanks for pointing it out.

I have gotten quite used to glancing at the status display in the VF

preserved through a power cycle, resets to 0 when you change  
batteries. I've never needed to change batteries in the middle of

The D and the Ds have 12-bit sensors and, through the magic of some
algorithms or whatnot, by the time the images are converted to a  
RAW file,

they are considered 16-bit files.  Some cameras have 14-bit sensors.


A 12-bit sensor reports the intensity of light falling on it as a  
number which is bounded by the range from zero to 2^12, or 4096. That  
means it quantizes the light into 4096 discrete steps. A 14-bit  
sensor would quantize intensities similarly but into 16,384 steps.  
The conclusion is that a greater bit depth nets you greater potential  
accuracy to the tonal resolution.


The data capture by the sensor (they're not images yet) is stored to  
a RAW format file "mostly" untouched. The Pentax D/DS bodies do  
virtually nothing to the sensor's data other than wrap it into a tag- 
structured file format (TIFF), write the camera's metadata to the  
file (time, date, camera type, resolution, parameters for in-camera  
JPEG rendering, blah blah blah), and also add the thumbnail and  
preview JPEG renderings to the file. The D files are larger than the  
DS files because the D files have absolutely nothing done to the  
sensor data, where I think the DS strips the extra zeros from every  
photosite's output (those four extra zeros are the result of storing  
2 bytes data instead of 1.5 bytes of data for every photosite). John  
Francis will likely point out what it actually does if I've gotten  
that incorrect, but the essence is that very very little has been  
done with the data from sensor to RAW format file in the Pentax  
bodies: it has not been "converted", just written out along with  
ancillary data. (Canon and Nikon DSLR bodies evidently do more  
processing on the RAW data, including (I've heard) some sharpening  
and compression (lossless).)


It's only when RAW conversion is performed and the data is written  
out to an RGB rendered file format (TIFF or .PSD) that the data has  
been transformed to a "16bit" representation. This conversion is  
somewhat more complicated to describe, but essentially the sensor is  
just a photon counter with a linear gamma ... your eye sees light  
which has been gamma converted, expanded and compressed adaptively  
based on illumination level and intent ... so the RAW conversion  
process is designed to transform the sensor data in a similar way. It  
also uses the Bayer matrix of RGB values that the data was collected  
with to interpolate an approximate color value, in RGB primary  
colors, for each picture element (pixel). Each color is considered a  
'channel', thus we have the notion of "16 bits per channel" value for  
every pixel. So each pixel is actually represented as three 16bit  
numbers or 48 bits of data.


Depending upon the RAW converter and editing software, the 16bits per  
channel representation for 12 or 14 bit sensor data renders the 4096  
or 16384 steps from 12- and 14-bit sensors into the larger, 16bit  
quantization space, numbers from 0 to 65536 (or 0 to 32768, if the  
particular converter is designed to use only the positive signed  
numbers ... ). The larger data space contains all possible values of  
the two smaller data spaces and interpolation accuracy, even with  
using just the positive signed values, is very very close to perfect.


What kind of improvement might one see when using a camera with a  
14-bit sensor
compared to one with a 12-bit sensor, all else being equal.  I have  
heard
that dynamic range is improved, i.e., more shadow detail is  
available and
highlights don't fry as easily with more bits in the sensor. Of  
course, all
else isn't usually equal, so what other factors play significant  
role in

determining image quality, apart from lenses.


Total dynamic range is dependent upon the analog capability of the  
sensor to record light from minimum activation to total saturation as  
well as the ability of the digital system to represent those  
intensity values accurately. 14bits might not buy any more dynamic  
range, but it should allow more accurate modeling of tonal values.


Of course, the practical reason that 14bit sensors might provide more  
dynamic range is that all 14bit sensors to date are much more  
expensive than 12bit sensors and only available on much more  
expensive digital capture devices (like multi thousand dollar  
scanning backs, etc) that include substantially better supporting  
circuitry, better noise isolation, more accurate reportage of actual  
intensity values, etc.


The ultimate question here, from  practical point of view, is "how  
many bits of quantization are enough?" The more the merrier, assuming  
you can afford it. 14- and 16-bit sensor systems are wonderful, but  
for most pictorial photographic work you'd be hard pressed to see  
much benefit from the larger data space



It's also been stated that some cameras use a "lossy" system when
converting

Re: New Digital SLR Products From Pentax

2005-08-22 Thread Godfrey DiGiorgi
I find the announcement exciting, even though I did just buy my  
planned second body (another DS). The addition of C-AF in all  
exposure modes and larger LCD are not enough to give me pause as I  
only paid $579 for the DS body, where  it will likely be some time  
before the DS2 is available at that kind of price. The small number  
of improvements to me indicates that the DS is quite good for the  
slot it fills and the competition it's up against.


To me it sounds like they've done a good detail update on their  
middle range body, now have a solid entry-level body in the DL model,  
and I expect the top of the line body will be updated soon.

BTW:
I picked up the Digital Photographer issue yesterday in which they  
compare the Nikon D70s, Canon 350D, Olympus E-300, and Pentax *ist  
DS. Aside from one error on the Pentax I noticed (they said it didn't  
do second curtain sync, which it does with a dedicated external  
flash), they presented their test data well. I think they then drew  
the wrong conclusions: the DS is the only one in the group that has a  
pentaprism viewfinder, and to my reading the DS has the best noise  
performance of all of them. They remarked on how nice the DS was in  
the hand too.

Re: Problems With *istDS USB Transfers

2005-08-22 Thread Godfrey DiGiorgi
The greatest likelihood, if you're using NiMH batteries, is that they  
are unable to sustain the power demanded by the transfer  
consistently. NiMH batteries seem to be best at modest duration  
bursts on power delivery. Pentax recommends using the external power  
supply when connected to a computer for file transfer.


This is conjecture ... if the problem is happening when you're  
connected and using known good CRV3 or AA Lithiums, then I don't know  
what the problem might be. I use a card reader, and have always done  
so. I use a Belkin 8-in-1 USB 2.0 reader. For $25, I find it very  
convenient and reliable; I don't like to have to keep plugging and  
unplugging my camera from the computer.

Re: What Would Make a DSLR "Obsolete"?

2005-08-23 Thread Godfrey DiGiorgi

This requires a definition of obsolete. The one I use is:
"A product is considered obsolete when it is no longer produced, that  
is, when it is replaced by something else by the original  
manufacturer or by another manufacturer."


By that definition, my Nikon FM was obsolete as soon as the FM2 model  
appeared. I bought the FM body, used, after the FM2 appeared on the  
market and used it for another 19 years. Someone else bought it after  
me and, presumably, is continuing to use it.


Obsolete does not imply not used or not usable.

Usability is gated by battery availability (not a problem), storage  
(not a problem) and software compatibility (not a problem). Also by  
reliability and durability ... so far (8000+ exposures on the DS  
body) I have seen little evidence of poor reliability or durability.


Most people these days seem to think of obsolete as meaning they must  
have the latest model or what they are using is unusable. The ramp up  
to current DSLR technology has been steep, but my feeling is that the  
industry passed a plateau point with the introduction of the Canon  
10D three years ago. I consider nearly any DSLR of that generation  
and beyond to be just as future usable as any 35mm SLR I've ever  
owned. No longer state of the art in speed, possibly no longer the  
best in noise, etc, but still perfectly usable for a long time  
despite being obsolete.


Regards:

Battery - AA and CRV3 will be with us forever, practically speaking.

Storage - There are already MILLIONS of flash storage cards in the  
world, each of which can be used for thousands of write/erase cycles.  
Just one represents at the very least 100,000 potential exposures in  
its lifetime. It will be a very very long time before there are no  
flash storage cards left to use.


Software - The software in use today for the handling of the storage  
medium is all standards based ... USB protocol connectivity, FAT16  
and FAT32 file system. That's not going to go away any time soon ...  
I can still read and write DOS floppies from 1982 (although I haven't  
in some years now) ... and new emergent file system standards  
generally speaking include compatibility to read older standards.  
Image formats like JPEG will be around practically speaking forever.  
Decoding and converting the Pentax RAW file format is something now  
encapsulated in open source C language code (dcraw by Dave Coffin) so  
even if current software products were to disappear entirely, someone  
could recompile a RAW converter utility on whatever operating system  
was then in place.


Nothing to worry about, in my opinion. This technology is here to  
stay, and I warrant will be feasible to use for the remainder of my  
lifetime. Advantageous, probably not: advances in camera technology  
and my desire to obtain better quality/perform will likely have me  
buying something new again at some point. But I do suspect that  
today's digital SLR bodies will be just as useful into the future as  
film SLR bodies will. When film manufacturers give up their last gasp  
and close down production due to lack of profits, and the last roll  
of film is consumed, that's it as there is no reusability in film  
storage media.

Re: istDS Flash Question

2005-08-23 Thread Godfrey DiGiorgi
Yes. Just set the flash to Manual using the Fn button menu. That's  
how mine's set. The flash will only be enabled when you press the  
button to open it manually. I've never had it set to anything  
else... ;-)


When the shutter speed drops below a threshold (still don't know  
whether it's focal length sensitive or not...), the camera will light  
the flash warning at the bottom of the viewfinder as a suggestion.  
It's barely visible, certainly not annoying, and serves as a helpful  
reminder if you're not paying attention to explicit shutter speed to  
hold the camera steadily.


With the DS, if you mount a manual focus lens and have the focus mode  
set to AF, the shutter will not release unless the focus confirmation  
system thinks it's in focus and lights the green confirmation  
indicator at the bottom of the viewfinder. Easy to ignore it and  
defeat the problem: just flip the switch to MF and ignore the  
indicator light. I often turn off the focus point indicator too when  
using a manual focus lens as it will always indicate focus on the  
center point, that's in the Custom Settings menu, "Superimpose AF  
area"...


The DS has a number of things when set to its "idiot mode" defaults  
to help a novice from not making exposures accidentally that will be  
crappy. Luckily, each and every one of them can be turned off easily,  
and they stay that way.

"Have I said how much I like this camera today?" :-)

BTW:
The FA35/2 is a super match to the DS ... Speed, size and weight are  
perfect for a normal lens. The AF is very quick and sure, and its  
imaging qualities are superb. On manual focus, it has a light,  
smooth, sure feel, and is contrasty enough to snap in and out of  
focus beautifully. I'm very glad I bought this lens, it is a perfect  
complement to the FA20-35 and F50/1.7.


(I'm sure the FA28/2.8 is too, for a wide-normal focal length. I'm

Re: Feedback on FA 28-70 F4.0 AL

2005-08-23 Thread Godfrey DiGiorgi
The scuttlebutt hearsay on this lens is that they are prone to  
element separation due to some quality control issues in assembly.  
That said, if you got a good one, the other scuttlebutt I've heard is  
that a good one is superb. For a one-stop light loss compared to the  
f/2.8 model, I'd much rather have the light weight and compact size  
of the f/4 model, presuming that a good one was actually what the  
scuttelbutt hearsay claims. (I don't own one, but one of my local  
Pentaxian user friends does and he loves it... obviously, he got a  
good one. ;-)


That said, the FA28-105/3.2-4.5 AL IF seems to be just as good a  
performer in the 28-70 focal length range (at least), is a little  
faster when wide, nets a little more reach at full tele, and costs  
only $210 new. It's also small and light. So if the one you bought  
does turn out to be damaged somehow, there are other good,  
inexpensive options.

The San Francisco organization photoAlliance is hosting their third
annual "Slide Slam!" this Friday evening. I've never been to one
before, thought it might be a giggle.. Details are on this page:

  http://www.photoalliance.org/

I'm busily pulling 10 photographs to submit on CD...



Godfrey, I'm interested in hearing how this slide slam thing goes.  
Could

you report back afterwards? I'd seriously like to consider organizing
something like this in Pittsburgh so I'd be curious about how the
logistics and organization are set up.


Okay, sorry not to get to this sooner but it's been busy around here.

The PhotoAlliance Slide Slam was a fun event. At 6pm or so they  
started registration. $20 per person paid for a BBQ dinner and use of  
the facilities at San Francisco Academy of Art. In registration, each  
participant delivered their photos to the folks at the table ... 10  
slides or 10 JPEG images on a CD.


For the slides, they were loaded into carousel trays with a title  
slide with the photographers name and a blackout closing slide. For  
the JPEGs, they were loaded into a PowerBook running iPhoto, again a  
title slide and a blank slide were added to the 10 photos.


No theme was suggested, no sizing information for the digital images  
was provided. People brought a wide variety of work in both slides  
and digital images. I put together 10 half-rez (1500 pixels down the  
long axis) JPEGs at about Photoshop's #8 quality setting. I drew my  
set of 10 from the PAW 2005 People & Portraits gallery work in  
progress, so all of mine were B&W renderings.


All that took a bit of time for the crew to set up, while dinner was  
going on and general socializing went on. It was fun: met a few  
interesting folks, and two of my friends showed up as well. At 8:45,  
the group was moved to the auditorium where a digital projector and a  
slide projection system were setup. Unfortunately, the high quality  
digital projector was out for some reason so they had to make do with  
a small portable unit.


The presentation was very very informal: basically, photographers  
were invited to speak if they chose to when their slide photo set was  
presented, and questions comments were welcomed. Each photo was shown  
for 10 seconds in sequence, and 7 judges were taking notes and  
informally keeping track of what they felt were outstanding photos.  
40 participants' sets of 10 photos were in the agenda, about an hour  
and a half viewing time given a few stops here and there.


The work presented was all over the map in content. Only a few  
photographers were prepared to speak to their work (I spoke fairly  
briefly as to what the project was about, etc). There were a few  
places where some music or speaking were sorely needed to help the  
display along...


The digital photos displayed reasonably well, considering the lack of  
a color managed projection system. Colors were off, my B&Ws' subtle  
tonalities were somewhat poorly rendered; what seemed to display best  
were color graphically oriented images with strong colors/bold  
compositions. But overall they were good and the display ran without  
a hitch.


The slides ran next. Speaking objectively, the slide projection  
system (which *was* the Art college's high-quality system) was  
nowhere near the quality of the portable digital projector: constant  
problems with focus, with slide handling, etc. Even the color was  
poor by comparison; the difference was quite striking. In my opinion,  
the slides would have been much better rendered if they'd been  
scanned and displayed as digital images.


When the viewing was done, the judges presented three awards (no, I  
didn't get one, but I wasn't expecting to... ;-) and a lot of the  
folks hung around a while discussing the work they'd presented.


It was a fine evening, first time I've participated in one of these,  
and I learned quite a bit about this organization and the other  
participants. My friends who were there with me and I are now quite  
interested to do a couple of these events ourself, locally here.  
We're thinking to put a little more structure into the event:


- Regardless of whether the originals are film or digital capture,  
the photos will be accepted

   for display only in digital form.
- Photographers will be given a time period and required to talk  
through their presentation,

   with manual remote control of the projection equipment.
- Anyone who would like to will be encouraged to have their photos  
available for viewing
   after the primary presentation, either by display on a laptop or  
in prints or whatever.
- All submissions will be required to be in the day before so that we  
can all be ready to go

   without the long setup period.
- The digital projector will be color managed.
- The number of presenters will be limited to keep the total group  
presentation to one hour.

That seems too closely related to a conspiracy theory. ;-)

No, the challenge to manufacturers like Nikon and Canon and Pentax,  
et al, is this: they had a large range of existing good lenses  
designed for film's characteristics and a 24x36mm format. Digital  
sensors, aside from being very expensive as the area grows, have  
different characteristics. The ideal lens mount for a digital sensor,  
and the ideal lens design for a digital sensor, takes into account  
that the light path should be more nearly orthogonal to the sensor  
even at the edges of the frame ... this implies a lens design which  
"straightens" the light path, and a larger mount.


The best compromise to allow compatibility with older lenses as well  
as achieve the quality and price points required by the digital  
camera is to reduce the size of the format. Moving to approximately  
half-frame size allowed the vast majority of existing lenses to work  
well, does not increase DoF excessively, and generally allows a  
photographer's kit to remain the same with the addition of one-two  
additional, shorter focal length lenses. A side benefit is that those  
additional lenses (and any others designed exclusively for coverage  
of the half-frame format size) can be smaller, lighter, and less  
expensive for their focal length and speed.


These decisions were made up to 8-9 years ago. Sensor chip technology  
has been very very fast paced in the past decade. Canon, having their  
own chip design/fab system, see a market advantage in being at the  
cutting edge of the technology and produce new designs faster than  
all the other vendors. I don't know whether they foresaw this way  
back in 1985, but the EOS mount is unarguably the most suited lens  
mount for 24x36 format sensors, having the largest diameter and the  
shortest registration of any modern AF SLR, as well as fully  
electronic coupling of all the lens controls to the body. This serves  
the double purpose of fulfilling Canon's take on the backwards  
compatibility game (everything in the EOS system is backwards  
compatible, presuming we discount the small selection of EF-S lenses  
designed specifically for the smaller format sensor cameras) and  
allows them the greatest flexibility in designing larger sensors to  
allow recouping the lens design/manufacturing cost investment.


That said, EOS bodies and lenses are amongst the bulkiest in the  
business. The Rebel film bodies became featherweight by dint of use  
of very lightweight plastic structures, pentamirrors, etc, and  
they've downsized the 20D and 350D/XT bodies nicely, but that does  
not reduce the size of the lenses these bodies must carry, which are  
designed for 24x36mm coverage.


For me, one of my biggest priorities, once past a certain assumed  
level of resolution and noise qualities, is not speed or fancy body  
coverings, bazillions of features ... It's size and weight of the kit  
I need to carry. My working style in the past was nearly always one  
body with two/three lenses in the bag or two bodies each fitted with  
a single lens. I like to walk all day with the kit and photograph the  
subjects I aim for in a fluid fashion, without being too obtrusive or  
constrained by fatigue. Four to six lbs is what I want the entire bag  
of gear to weigh, and I don't want the bag to be overly large or  
obtrusive in appearance.


The Pentax DSLRs, with a half-frame format sensor, net the quality  
and the noise level I need for photographic quality, and the lenses/ 
bodies are compact and light. The very inexpensive yet high quality  
50mm f/1.4 lens is a perfect portrait tele, the excellent and also  
tiny 35/2 is a perfect normal; the excellent 14/2.8 is a superb  
ultrawide at the widest FoV point that I personally find useful and,  
for such a short focal length rectilinear with that speed, it is not  
only small but low priced compared to the 24x36 format coverage 14s  
from Nikon and Canon. I can fit two bodies, each with a lens, or one  
body and three lenses into a 6lb bag.


I'm all for more resolution, lower noise, and even a larger sensor.  
But I want it to fit my overall needs as the current system bits do.  
As I said before, a 3:4 or 4:5 proportion format makes good sense to  
me for my compositional tendencies: it uses more of the lens' image  
circle and implies less wastage of pixels in cropping, and I could  
easily see an 8-10Mpixel sensor at 18x24 or 20x24 (for full  
compatibility with current DA series lenses) being quite attractive.

Understandably, either the sensor was of comparatively poor design,

The MZ-D experiment was replicated, whether anyone said anything

Contax even shipped a camera based on the Phillips sensor ... and it  
was a disaster. Why? Because whether or not the lens mount is ideally  
suited to the sensor, the compelling desire to use the same lens line  
is worth big bucks.


The opportunity to sell new, smaller format coverage lenses  
exclusively for half-frame sized digital sensor cameras is not a shoe- 
in for profit because, until the release of the Canon 300D, DSLRs  
sold in tiny tiny numbers compared to film SLRs and fixed lens  
digital cameras. Any company producing lenses specific to the reduced  
size format, until this very year, has probably not yet seen a  
substantial profit from their design and manufacturing process  
investment. The 300D, the DS, the D70, and the other follow-on DSLR  
bodies under the US$1000 price point will now change that scenario. I  
think Pentax is actually in a sense at the forefront of this amongst  
the SLR manufacturers, now producing six or seven lenses tailored for  
the 16x24mm sensor format (DA14, 16-45, 18-55, 40, 50-200, upcoming

Today, I realized when this can be helful (to me at least).
Sometimes, AF of Tamron 70-300/4-5.6 in low light
with the focal length close to 300, tends to hunt and miss if
the original focus position was faraway from the target.
What works for me is to "preset" it manually to the right range,
so that it AF quickly and more reliably.
In this case the functionality of the "OK" button can help.


Interesting. When the light gets down to the point where the AF hunts  
too much, I just switch to MF and do the focusing myself. Different  
way of working, I guess.

Applying statistics to shooting like this isn't really sensible. My  
"days" tended to be 13-16 hours out and about with the camera with me  
at all times. Exposures got made in bursts, perhaps at times several  
dozen in a few minutes with an interesting scene or subject matter,  
and at other times a couple now and then as scenes and subjects  
happened. Several days had virtually no shooting at all too, as I was  
in transit or tired or just not motivated. All told, I averaged 133  
exposures for every day of the trip (21 days total), but my average  
on shooting days was about 250.


...
An exposure every 12 seconds or so doesn't seem like much thought  
went into
composition or framing ... but then, I can see the desire to shoot  
a lot

and shoot fast in some circumstances.


Exactly. I don't walk around like an automaton and press the button  
every 12 seconds. I look at a subject or scene carefully, then shoot  
as many frames as I think I need to get what I want out of it. Some  
scenes only one exposure is made, and that's all the opportunity  
there might be. For other scenes and situations I might make three  
dozen looking for "the one", with different settings.



Speaking only for myself, a slower
approach often seems to work better.  Anyway, there's a difference  
between
a burst of enthusiastic shooting and making a lot of exposures  
consistently
over a protracted period of time.  I don't think I've the stamina  
for it.

But then again, maybe with a digi I will ...


Remember that there's no downside to making more exposures with a  
digital capture camera. Any waste exposures can be deleted and the  
storage card re-used.


It invites a more opportunistic approach than film does ... I've  
sometimes been fascinated with doing a study on something that I KNOW  
has only 1 chance in 500 of making it as a photo, but I can spend a  
hundred exposures on it, trying different angles, different ideas,  
without any need to reload film or worry about another $20 worth of  
film and processing being wasted. When I work with a tripod on static  
subjects, I tend to make a lot of exposures at slightly different  
exposure settings, to determine which nets the best expression in  
tonality and color. When I'm street shooting, I might make fewer  
exposure changes but more total exposures to capture nuances of  
expression and angle of approach.



Shel (visions of gigabytes dancing through my head)


Yes, it involves gigabytes of image data. I returned from my trip  
with 28-29G worth of exposures to work on. I've currently identified  
and sorted out about 8 themes from that work, suitable to develop  
into shows and books, which is what I'm working on now.


When I took the Hasselblad SWC with me on a similar trip in 2002, I  
consumed about 20 rolls of 12 exposure film in a two week period.  
Lots of excellent work came out of it, but the keeper percentage  
(keepers/total exposures) turns out to be pretty similar. With a  
faster camera, then, I am more productive in unit time. ;-)

Re: Film scanner question

2005-08-25 Thread Godfrey DiGiorgi
MAC is a brand name for machine hand tools, like crescent wrenches,  
spanners, screwdrivers, etc. ;-)


FYI:
Mac OS X is a UNIX-based operating system, with full-time virtual  
memory. Executables are file-mapped extensions to the physical  
address space. Each process on Mac OS X is given an independent  
address space at runtime, to the limit of the addressable space  
provided by the processor and memory controller. Memory is paged into  
and out of RAM as needed. The more physical RAM is provided, the less  
need for paging and thus the better the performance. When paging is  
necessary, the transfer speed of the hard disk becomes important and  
can contribute to system performance to a great degree.


For serious work on Mac OS X with Photoshop, I recommend 1G RAM as a  
minimum with a fast hard drive, and at least 10-20G bytes of free  
space on the drive. The more RAM, the more free space and the faster  
the drive, the better. For less seriously heavy duty work, a 512-768M  
RAM system and a decent drive will suffice too. I haven't found too  
much performance benefit with 2G RAM over 1G RAM, a faster-bigger  
hard drive generally makes a bigger difference, but it helps if  
you're working with a lot of very large files.

The issue is that different B&W film and developer combinations have  
different spectral responses, gamma curves, etc. If what you are  
looking to do is emulate a particular B&W film and do it as

TheImagingFactory.com and digitalsilver, as well as others, have

However, all they're doing, really, is manipulating the balance of  
the channels, much like using the Channel Mixer or one of the several

I tend to prefer to work the tonalities myself, rather than trust to  
a plug-in, because I want to be able to achieve a particular set of  
response curves and reproduce it with a wide variety of capture  
settings reliably, and because I want to understand precisely what  
the transformation performed was. I also don't like paying for

close to 60mm for 35mm film cameras, so this might do the trick on

on the

I'd like to at least see it.  Let's try to get together when you

Huh? Full control of both body and lens will be possible, and you'll

I know the pod won't display RAW files, but that's ok. I just want  
to dump RAWs. I'm looking at the Belkin media reader. Seems it will  
work nicely at firewire speeds. But it is quite pricey.


And then there are camera USB adapters. The Apple camera adapter  
doesn't list the *istDS as compatible, but since it works as a mass

Does anyone have any advice, or first hand experience?


I'm not sure that the iPod Photos will transfer anything but JPEG

DS:

In Manual exposure mode on the, the thumbwheel wheel controls both  
aperture and shutter speed. Turned by itself, set shutter speeds from  
30 seconds to 1/4000 second. Press the "+/- Av" button and the  
thumbwheel sets the aperture.


And...

In Av mode, the thumbwheel controls the aperture. Press the "+/- Av"  
button and the thumbwheel controls the EV compensation. In Tv mode,  
the thumbwheel controls the shutter speed, and EV compensation is  
controlled same as in Av mode.


In either of Av or Tv exposure modes, if you frame what you want to  
meter on and press the AE-Lock button, rolling the thumbwheel changes  
the aperture or shutter speed respectively, and it holds the same  
metered EV value by shifting the shutter speed or aperture to suit as  
well.


In Manual mode, frame what you want to meter on and press AE-Lock:  
the camera will set a shutter speed to match the current aperture  
setting and also display 0.0 EV in the lower right corner of the  
viewfinder display. Changing the aperture or shutter speed will now  
display the change from what you metered within a range of +/-3.0 EV.

Re: iPod photo storage

I was not referring to the use of the iPod as a FireWire/USB 2.0 hard  
drive, attached to a host computer. I do that with mine all the  
time ... I keep an encrypted copy of my financial database and other  
critical files on an iPod as a backup in case of my systems' hard  
drive failing (as well as in other places, of course).


I was referring to the use of the iPod Photo as a standalone image  
storage device. The latest versions of the iPod Photo can attach  
directly to a camera and initiate the transfer of image files to its  
disk. However, I am not sure that it will transfer anything but JPEG  
files ... that is, it will not transfer .CRW, not .NEF, not .PEF,  
etc, RAW format files in this mode. I'm not sure about that, however,  
so it's something to check with the specs of the iPod Photo software  
before relying upon it.

I've never tried RAW file, but I have transfered text files from my

Interesting perception. It's hard to read the facial expressions of a
