 This is an interesting website which shows you where all the bombs landed in
 London during the blitz. The link is set up with the coordinates round my
 house, on Azof Street:
 http://bombsight.org/?#16/51.4890/0.0063

 When I first moved here the site at the junction with Christchurch Way was
 still derelict, 50 years after the war. It's been built on now. Some of the
 older people still living on this street were here throughout the war, while
 the bombs were dropping round them. From time to time while people are doing
 building work an unexploded bomb still turns up. The most recent near to me
 was on the riverside path about 10 years ago.

 When you zoom out of the map it's quite shocking to see how many bombs fell
 in such a short time. We gave as much as we got, of course.

Very interesting Bob.

A sad story: My mother's family was living in Devon and they had a
little girl from the East End billeted with them as part of the
evacuation of children. Her father, a docker, came to visit and she
innocently told him to take his elbows off the table as it was bad
manners. He said something like I'm not having my daughter growing up
with middle class airs and graces. He took the girl back home with
him. After the war my mother tried to track them down and heard that
the whole family had been wiped out by a direct hit on their Anderson
shelter a couple of days later.

 From: Alexandru-Cristian Sarbu alexandru.sa...@gmail.com
 
 Now everywhere I can hear them talking about stuff like growth or
 doubling the sales in 2013. I'm hearing they hired back RD engineers,
 to make up for those fired by Hoya. They have 2-years roadmaps
 totaling 8 K-mount lenses + 1 TC, 4 645D ones and 3 for Q; and, most
 important, they're on track with the execution.
 
 
 Alex, respectfully, I don't have that kind of insider information on
 Pentax, so where do you obtain it? If their road map doesn't contain a
 24 MP APS-C body, a FF body and lenses, then they're missing the boat.
 I'm sure the market for either of those two cameras would dwarf the
 market for a 645D or a Q.


Tom,  

You've mentioned 24 MP a few times.  How large are you printing that you need 
24MP?

Also, what APS-C camera has that resolution?  4000x6000 pixels,  on a 16x24mm 
sensor, that gives 4um on a side for a pixel.
Using the diffraction calculator at: 
http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm

f/2.8 has an Airy Diameter of 3.7 um or about 1 pixel
f/5.6 has an Airy Diameter of 7.5 um or about 2 pixel
f/8 has an Airy Diameter of 10.7 um or about 2.5 pixel

The page says:
As a result of the sensor's anti-aliasing filter (and the Rayleigh criterion 
above), an airy disk can have a diameter of about 2-3 pixels before diffraction 
limits resolution (assuming an otherwise perfect lens). However, diffraction 
will likely have a visual impact prior to reaching this diameter.

In other words, with an AA filter, a 24MP APS-C lens will definitely be 
diffraction limited by f/8.0.  Without an AA filter, assuming that the lens is 
sharp enough, diffraction is probably having an effect by f/4 or f/5.6.

4um is 250/mm, which I understand works out to 125 lp/mm.  

Looking at DxOmark
http://www.dxomark.com/index.php/Lenses/Camera-Lens-Database/Nikon/Nikon-AF-S-Nikkor-35mm-f14G/(camera)/485
Nikkor 35/1.4  52 lp/mm
http://www.dxomark.com/index.php/Lenses/Camera-Lens-Database/Nikon/Nikon-AF-S-Nikkor-50mm-F18G/(camera)/485
Nikkor 50/1.8  53lp/mm
http://www.dxomark.com/index.php/Lenses/Camera-Lens-Database/Nikon/Nikon-AF-S-DX-Micro-NIKKOR-40mm-F28G/(camera)/680
Nikkor 40/2.8  is 49lp/mm

http://www.dxomark.com/index.php/en.../Lenses/Camera-Lens-Database/Pentax/smc-D-FA-MACRO-100mm-F2.8-WR/(camera)/676
Pentax DFA macro 100/2.8  is 46 lp/mm
http://www.dxomark.com/index.php/en.../Lenses/Camera-Lens-Database/Pentax/Pentax-smc-DA-35mm-F28-Macro-Limited/(camera)/676
Pentax DA 35/2.8 macro is 46 lp/mm

It seems as if you want a sensor that has approximately twice the resolution of 
a very good prime lens, which correlates roughly with the Nyquist rate, which 
would mean that you would never need an anti-aliasing filter, because even 
without getting into diffraction limiting, you're already past the Nyquist rate.

Is this why you feel that 24 MP is so necessary in an APS sensor camera?

Bay photo seems to use 250 dpi as a print resolution:
http://www.bayphoto.com/bayweb/pro_fileprep.htm

Which, interestingly works out to 16x24 inches.  However using the scaling of 
the graph they use for Minimum Pixel size to yield good prints, they seem to 
work with about five printer dots per pixel, which means that with a 4000x6000 
sensor, you should be able to print at 80x100 inches.  How often do you make 
prints that large?

On the other hand, lower resolution would give more surface area per pixel, 
which would increase both dynamic range, and signal to noise ratio.  In my 
photography, I find myself running up against these two far more often than I 
run out of resolution in printing.  By Bay Photo's chart, my K-5's 14 MP is 
good for something like a 60x80 inch print.  A 5x7 for people who measure their 
prints in feet, rather than inches.  I might be missing something here, because 
I've never printed much larger than 18x24.

Although you implied market forces require that sort of resolution, which means 
that the average photographer who uses their SLR as an expensive point and 
shoot is printing that large.  Or, are you just saying that it is one of those 
marketing things, where people aren't satisfied with less than 300 cubic inches 
of displacement in their car's engine, whether or not the customer would ever 
use the power, or whether or not a car with a much smaller engine would 
outperform it?

As I see it, I'm either not technically inclined enough, and I am totally 
missing the analysis of why16MP, or even 12, is not enough, and why a camera 
needs 24 MP in order to be marketable.  Or, it could be that I'm far too much 
of a geek, and am missing something critical by only looking at the physics of 
the situation.  The latter is quite possible, because I also can't understand 
why suburban housewives in Coastal California where it never snows, need a 
5,000 pound four wheel drive  SUV, that seats eight, has a 6 liter motor that 
puts out 300 hp.

Re: Bomb sight

2012-12-09 Thread Daniel J. Matyola
It's quite possible the bomb didn't go off because it wasn't armed
before it was jettisoned.  I was a bombardier/Navigator and an
Airborne Radar Officer in the USMC many years ago.  Most of the bombs
we used and trained with had to be armed before they were dropped.
One wouldn't arm a bomb before jettisoning it over friendly or neutral
territory.  I can still explode under some unusual circumstances, but
usually an unarmed bomb is just dead weight.  Of course, something
that heavy can still cause terrible damage, even if it doesn't
explode.

 A view from the other side of the channel:

 When I was five-six, (1950) my family finished up a three-year stint in
 Northern Greece and headed back to the States. A three-week tour through
 Europe, then a boat back home. One of my vivid memories from that trip was
 seeing block after block of damaged buildings in Germany and asking my
 father what had happened to them. They were bombed during the war and
 haven't been able to rebuild yet. Many years later, my major advisor from
 graduate school published a personal memoir of sorts [into the Fire by
 Siegfried Streufert]. His father was one of the anti-Nazi senators who went
 back home to Northern Germany in the mid 1930's (?) and was then part of the
 resistance. Siegfried tells of what it was like as a child living under the
 threat of bombers, and then later the frustration that the Allied troops
 didn't understand that many Germans saw them as liberators, not as
 conquerors. Bob, the graphic you shared really brings back those stories and
 is a reminder that this wasn't a sometimes thing, but that everyone was at
 risk in every neighborhood for months and months and months. A horrible way
 to live and a testament to universal stupidity.

 Very interesting Bob.

 A sad story: My mother's family was living in Devon and they had a
 little girl from the East End billeted with them as part of the
 evacuation of children. Her father, a docker, came to visit and she
 innocently told him to take his elbows off the table as it was bad
 manners. He said something like I'm not having my daughter growing up

 him. After the war my mother tried to track them down and heard that
 the whole family had been wiped out by a direct hit on their Anderson

Alex, respectfully, I don't have that kind of insider information on

24 MP APS-C body, a FF body and lenses, then they're missing the boat.
I'm sure the market for either of those two cameras would dwarf the
market for a 645D or a Q.


Tom,

You've mentioned 24 MP a few times.  How large are you printing that you need 
24MP?

Also, what APS-C camera has that resolution?  4000x6000 pixels,  on a 16x24mm 
sensor, that gives 4um on a side for a pixel.
Using the diffraction calculator at: 
http://www.cambridgeincolour.com/tutorials/diffraction-photography.htm

f/2.8 has an Airy Diameter of 3.7 um or about 1 pixel
f/5.6 has an Airy Diameter of 7.5 um or about 2 pixel
f/8 has an Airy Diameter of 10.7 um or about 2.5 pixel

The page says:
As a result of the sensor's anti-aliasing filter (and the Rayleigh criterion 
above), an airy disk can have a diameter of about 2-3 pixels before diffraction 
limits resolution (assuming an otherwise perfect lens). However, diffraction 
will likely have a visual impact prior to reaching this diameter.

In other words, with an AA filter, a 24MP APS-C lens will definitely be 
diffraction limited by f/8.0.  Without an AA filter, assuming that the lens is 
sharp enough, diffraction is probably having an effect by f/4 or f/5.6.

4um is 250/mm, which I understand works out to 125 lp/mm.

It seems as if you want a sensor that has approximately twice the resolution of 
a very good prime lens, which correlates roughly with the Nyquist rate, which 
would mean that you would never need an anti-aliasing filter, because even 
without getting into diffraction limiting, you're already past the Nyquist rate.

Is this why you feel that 24 MP is so necessary in an APS sensor camera?

Bay photo seems to use 250 dpi as a print resolution:
http://www.bayphoto.com/bayweb/pro_fileprep.htm

Which, interestingly works out to 16x24 inches.  However using the scaling of 
the graph they use for Minimum Pixel size to yield good prints, they seem to 
work with about five printer dots per pixel, which means that with a 4000x6000 
sensor, you should be able to print at 80x100 inches.  How often do you make 
prints that large?

On the other hand, lower resolution would give more surface area per pixel, 
which would increase both dynamic range, and signal to noise ratio.  In my 
photography, I find myself running up against these two far more often than I 
run out of resolution in printing.  By Bay Photo's chart, my K-5's 14 MP is 
good for something like a 60x80 inch print.  A 5x7 for people who measure their 
prints in feet, rather than inches.  I might be missing something here, because 
I've never printed much larger than 18x24.

Although you implied market forces require that sort of resolution, which means 
that the average photographer who uses their SLR as an expensive point and 
shoot is printing that large.  Or, are you just saying that it is one of those 
marketing things, where people aren't satisfied with less than 300 cubic inches 
of displacement in their car's engine, whether or not the customer would ever 
use the power, or whether or not a car with a much smaller engine would 
outperform it?

As I see it, I'm either not technically inclined enough, and I am totally 
missing the analysis of why16MP, or even 12, is not enough, and why a camera 
needs 24 MP in order to be marketable.  Or, it could be that I'm far too much 
of a geek, and am missing something critical by only looking at the physics of 
the situation.  The latter is quite possible, because I also can't understand 
why suburban housewives in Coastal California where it never snows, need a 
5,000 pound four

Most of the current entry level APS-C DSLRs are 16-18 Megapixels.  The
new Nikon D3200 is 24 Megapixels.

For the most part it's marketing.  Most consumers will never know the
difference.  Most won't make anything bigger than an occasional 8x10,
if they print at all.  Those that crop their photos will appreciate
the extra pixels.

Larry, you wonder why more megapixels? I appreciate your analysis of pixel 
size, diffraction issues, etc. (really, I do), but I think you missed the key 
underlying element: it is all a conspiracy between the camera vendors and 
manufacturers of hard drive storage units. 

You also say ...I also can't understand why suburban housewives in Coastal 
California where it never snows, need a 5,000 pound four wheel drive  SUV, that 
seats eight, has a 6 liter motor that puts out 300 hp. This is an example of 
great forethought and a demonstration of the purchasing acumen of American 
consumers; after all, someday during the 3-5 year lifespan of the vehicle they 
may have a bunch of kids and may want to drive to Lake Tahoe for a ski weekend 
and they may need the 4WD. Buying for that possibility means that they avoid 
regret later. And they avoid the expense of a weekend rental vehicle. And 
besides, it looks cool.

 f/2.8 has an Airy Diameter of 3.7 um or about 1 pixel
 f/5.6 has an Airy Diameter of 7.5 um or about 2 pixel
 f/8 has an Airy Diameter of 10.7 um or about 2.5 pixel
 
 The page says:
 As a result of the sensor's anti-aliasing filter (and the Rayleigh criterion 
 above), an airy disk can have a diameter of about 2-3 pixels before 
 diffraction limits resolution (assuming an otherwise perfect lens). However, 
 diffraction will likely have a visual impact prior to reaching this diameter.
 
 In other words, with an AA filter, a 24MP APS-C lens will definitely be 
 diffraction limited by f/8.0.  Without an AA filter, assuming that the lens 
 is sharp enough, diffraction is probably having an effect by f/4 or f/5.6.
 
 4um is 250/mm, which I understand works out to 125 lp/mm.

 It seems as if you want a sensor that has approximately twice the resolution 
 of a very good prime lens, which correlates roughly with the Nyquist rate, 
 which would mean that you would never need an anti-aliasing filter, because 
 even without getting into diffraction limiting, you're already past the 
 Nyquist rate.
 
 Is this why you feel that 24 MP is so necessary in an APS sensor camera?
 
 Bay photo seems to use 250 dpi as a print resolution:
 http://www.bayphoto.com/bayweb/pro_fileprep.htm
 
 Which, interestingly works out to 16x24 inches.  However using the scaling of 
 the graph they use for Minimum Pixel size to yield good prints, they seem to 
 work with about five printer dots per pixel, which means that with a 
 4000x6000 sensor, you should be able to print at 80x100 inches.  How often do 
 you make prints that large?
 
 On the other hand, lower resolution would give more surface area per pixel, 
 which would increase both dynamic range, and signal to noise ratio.  In my 
 photography, I find myself running up against these two far more often than I 
 run out of resolution in printing.  By Bay Photo's chart, my K-5's 14 MP is 
 good for something like a 60x80 inch print.  A 5x7 for people who measure 
 their prints in feet, rather than inches.  I might be missing something here, 
 because I've never printed much larger than 18x24.

Where do you see the difference in the attached file?  Has it already 
been reduced in size before sending the email?  Then it's happening in 
your email client and that's where you'll find any avoidance measures.


If you're not noticing it until after it's been received by someone, it 
could be happening at any of several points along the way.

Re: How do I determine the resolution---dpi---of an image?

2012-12-09 Thread Stan Halpin
Resolution, dots per inch,  is meaningless on its own.
If you know the target size, then you can calculate the number of dots you need 
(eg, 8x10 would be 2400x3000 dots = 7,200,000 dots). Which more or less 
translates to a file of 7.2mb.
But a 1x2 image only needs 300x600= roughly 180kb. 

LR allows you to specify dpi when printing and it allows you to specify file 
output size when doing an Export. But you need to know the target print size, 
and you need to do the calculation to determine the necessary file size.

Uh oh. This sounds like a request from someone who doesn't know what
they're talking about. Output resolution (which is in pixels per inch,
not dots per inch) is independent of image dimensions (in pixels). You
need to ask them for either the pixel dimensions they want (which they
probably won't know) of what their intended print size is (in inches
or centimeters).

I have LR 3. Is there a way in it to determine the resolution/dpi --- 
I'm assuming they are equivalent---of an image? Is there a way to 
control the resolution/dpi when exporting the image?

You can control everything in the Export dialog. The parts of the
Export dialog are as follows (scrolling from top to bottom):

* Export location
* File Naming
* Video
* File settings (file format, color space, bit depth, etc.)
* Image sizing
* Sharpening
* Metadata
* Watermarking
* Post-processing

The first two items are at your own discretion. The third is
non-applicable.

File settings should, unless the recipient specifies otherwise, be
JPEG file format, sRGB color space, high quality (how high is up to
you)

Image sizing is where you set parameters for the pixel dimensions of
your exported image. You know that the output resolution needs to be
300 ppi (though it really doesn't matter - the recipient can change it
to any value they like) but you don't know what actual dimensions in
pixels or inches are required. This is the information you need to get
from the person you're sending the image to.

(I'd leave sharpening off and skip the Metadata, Watermarking and
Post-processing sections for this.)

Long Exposure Rule of Thumb

2012-12-09 Thread George Sinos
I was listening to one of the many photography podcasts recently and
heard someone mention this estimating technique.

He said he likes to make his night exposures at ISO 100 to minimize
noise, but zeroing in on the exposure time at that low ISO can take a
long time.

So, he makes his initial exposures at ISO 6400.  It turns out that the
exposures length in seconds at 6400 is pretty close to the length in
minutes at ISO 100.   For example, a 10 second exposure at ISO 6400
would work out to a 10 minute exposure at ISO 100.

Making the initial estimated exposure time at 6400 reduces the number
of test exposures he needs to make at ISO 100.

I had to make a little spreadsheet to convince myself. It's not exact,
but the error is relatively small.  Probably less than is necessary to
give you a good starting point at the lower ISO.

I don't do a lot of night or long exposure stuff and maybe this is
common knowledge to those that do.  I've been around a long time and
heard a lot of rules, but this one was new to me.

Suffers from Theriaultian blur?

If it suffers it's another type of blur, by definition!

;-)

The camera focused on the cars. But as I looked at the photo I liked how the 
cyclists are a bit soft (or.blurry); that's kind of how we feel sometimes, 
almost invisible to motorists. So I thought it works.

Others may have differing opinions.  :-)

Thanks for the comments, Marnie.

Glad you enjoyed the hats blog. Haven't really contributed much to that lately. 
Have a few hat pix kicking around but I've been concentrating on the messenger 
stuff lately.

RE: Files reduced in size when attached to email

2012-12-09 Thread Gerrit Visser
It is almost certain to be the email client at the sending end but it is
Apple so not sure. This link provides some suggestions to avoid or control
the resizing. Outlook on Windows has options that you can set and even then
you can tell it to give you a choice each time.

There is no way that your ISP will resize anything. It is the sender or
receiving email program doing the harm.

If you're email client is actually resizing your Jpegs I'd look into a

the attachment is too large, not decide for you and then alter the

 Subject: Long Exposure Rule of Thumb
 
 I was listening to one of the many photography podcasts recently and
 heard someone mention this estimating technique.
 
 He said he likes to make his night exposures at ISO 100 to minimize
 noise, but zeroing in on the exposure time at that low ISO can take a
 long time.
 
 So, he makes his initial exposures at ISO 6400.  It turns out that the
 exposures length in seconds at 6400 is pretty close to the length in
 minutes at ISO 100.   For example, a 10 second exposure at ISO 6400
 would work out to a 10 minute exposure at ISO 100.
 
 Making the initial estimated exposure time at 6400 reduces the number
 of test exposures he needs to make at ISO 100.
 
 I had to make a little spreadsheet to convince myself. It's not exact,
 but the error is relatively small.  Probably less than is necessary to
 give you a good starting point at the lower ISO.
 
 I don't do a lot of night or long exposure stuff and maybe this is
 common knowledge to those that do.  I've been around a long time and
 heard a lot of rules, but this one was new to me.

RE: Cameras and Photography

2012-12-09 Thread Bob W
 Larry, you wonder why more megapixels? I appreciate your analysis of
 pixel size, diffraction issues, etc. (really, I do), but I think you
 missed the key underlying element: it is all a conspiracy between the
 camera vendors and manufacturers of hard drive storage units.
 
 You also say ...I also can't understand why suburban housewives in
 Coastal California where it never snows, need a 5,000 pound four wheel
 drive  SUV, that seats eight, has a 6 liter motor that puts out 300
 hp. This is an example of great forethought and a demonstration of the
 purchasing acumen of American consumers; after all, someday during the
 3-5 year lifespan of the vehicle they may have a bunch of kids and may
 want to drive to Lake Tahoe for a ski weekend and they may need the
 4WD. Buying for that possibility means that they avoid regret later.
 And they avoid the expense of a weekend rental vehicle. And besides, it
 looks cool.

Re: Snapseed now available for Android and iOS version now FREE

2012-12-09 Thread Godfrey DiGiorgi
Returning to the product ...

I've been using the new version of Snapseed for a few days now.
Overall, it's pretty similar, aside from the new integrated Boogleplx
photo nonsense.

The biggest thing that changed for my use is that now the frames
section has a greatly expanded set of options, which are much nicer
than the previous ones. The only small downside to this is that they
seem to have removed any of the adjustability of the old frames
section. Not a problem since the new ones are better than the old
ones, but I do dislike that they've removed an adjustment capability.

Onwards we go ...

It's a neat trick, I like it.
One addition: I modify the low ISO setting to accommodate a maximum
exposure length of between 2 and 4 minutes. This seems to make the
best images for me, and fits within most of the SLR-class sensors'
maximum exposure length restrictions, for those cameras I own that
have them.

Re: Files reduced in size when attached to email

If you're email client is actually resizing your Jpegs I'd look into a
different email client.  You have no idea what criteria or how good the
jpeg engine was that the client decided to use.  A good client will warn
you that the attachment is too large, not decide for you and then alter
the attachment based on some arbitrary set of rules decided by a
programmer who has no idea what your intentions are.

Re: Long Exposure Rule of Thumb

2012-12-09 Thread John Sessoms
Another good one for night sky is divide 600 by the focal length of the 
lens to get the maximum exposure time that makes the stars still look 
like dots.


From: Godfrey DiGiorgi

It's a neat trick, I like it.
One addition: I modify the low ISO setting to accommodate a maximum
exposure length of between 2 and 4 minutes. This seems to make the
best images for me, and fits within most of the SLR-class sensors'
maximum exposure length restrictions, for those cameras I own that
have them.

Subject: Long Exposure Rule of Thumb

I was listening to one of the many photography podcasts recently and
heard someone mention this estimating technique.

He said he likes to make his night exposures at ISO 100 to minimize
noise, but zeroing in on the exposure time at that low ISO can take a
long time.

So, he makes his initial exposures at ISO 6400.  It turns out that the
exposures length in seconds at 6400 is pretty close to the length in
minutes at ISO 100.   For example, a 10 second exposure at ISO 6400
would work out to a 10 minute exposure at ISO 100.

Making the initial estimated exposure time at 6400 reduces the number
of test exposures he needs to make at ISO 100.

I had to make a little spreadsheet to convince myself. It's not exact,
but the error is relatively small.  Probably less than is necessary to
give you a good starting point at the lower ISO.

I don't do a lot of night or long exposure stuff and maybe this is
common knowledge to those that do.  I've been around a long time and
heard a lot of rules, but this one was new to me.

Well if you want to get technical about it Boris... :)


Well, it is my hobby, so I'd rather we did not go too technical, if you 
catch my drift here, Tom...



It's my opinion that what we see with Pentax right now, in their lack
of new products that solidly compete with the competition on multiple
levels, is that they are simply doing all they can at the moment with
limited resources. They're not dead, but you can provide a word if you
like...


Well, you may be right. It is being my opinion as well that as of few 
years ago Pentax virtually stopped innovating and turned towards the 
design/appeal dimension trying to carve for themselves new market niches 
where they could collect the dividends.


It would even seem (to me now) that the most recent price plunges they 
had to take are to some extent a proof to the above idea. Given that 
very often fashionable/designer clothes cost more not because they are 
more useful or more functional but rather by being of that specific new 
fab design, so high were the prices of Pentax Q and Pentax K-01.


Again, it is my personal view that both cameras were in fact a waste of 
some very valuable engineering resources within the company. Granted, Q 
sells good in Japan and Japan is indeed a very big market, but there are 
other markets out there. Well, never mind, I don't intend to question 
the marketing decisions of the guys in the mothership...



No FF 24 X 36mm body.
No Mirrorless ILC or EVIL body save for one being sold at 50% discount
No high end large sensor compact


Let me summarize it for you, please. Here goes: no response to 
innovative products by the competing companies. The last really fab move 
was 645D. But it took lots of time and it was some time ago while both 
market and the competitors move on.



They're really only competing in the APS-C arena and that's about it.
The 645D is just about out of everyone's price range including mine.
Was it ever relevant?


It was. Because if they could market it properly it gave image to the 
company. There was time that all Renault cars sold in Israel had 
markings of that Formula 1 team or whatever racing Renault is involved 
in. Obviously not the racing cars, these Renaults were, but the 
impression was there and it was in a sense attractive.


Additionally, it did give Pentax the complete product line in terms of 
various market segments. If you're a true pro and want to shoot Pentax - 
645D was (and still is) for you. It is mighty capable camera (or at 
least this is what I've been gathering from the photographs I've been 
seeing from it). But Pentax chose to fragment their resources between 
various other market segments...



The K5 and derivatives may be solid cameras in their own right. Having
used Pentax for 20 years I'd be lying and stupid to say they didn't
make a product that delivered good results.


Well, yes they are. It is just that in modern camera marketplace you 
have to keep dancing your breakdance or the competition will break your 
neck, pardon my pun here.



Fact's are they have only about 2% of market share and predictions are
it will decline.


Pardon my being blunt, I don't give a shit about the predictions. 
Although the fact that the fellow PDMLer couldn't properly repair their 
FA 135/2.8 lens is worrisome. By the way, I've had a bit of a trouble 
with my FA 20/2.8. Thankfully good men of Pentax Israel did their job 
giving me no reason to complain whatsoever.



If Pentax was working on a FF body they should certainly say so,
rather than hide it. As some have pointed out, the lack of a FF lens
line is problematic in that regard.


They couldn't. They've played themselves into the marketing zeitnot. 
They've announced not one but three cameras practically at once. Now, if 
they indicate that they plan to introduce FF camera and give time 
estimate for that, it will hurt the sales of their current offerings. 
And if they don't - well, it would mean pretty much business as usual. 
So they chose the easy road, so to say.


Again, all of the above is my personal view and I don't intend to 
convince anyone of it. I merely would like to make sure that my ideas 
are understood. That's all there is to it.


Boris

 From: Larry Colen l...@red4est.com
 
 Tom,
 
 You've mentioned 24 MP a few times. How large are you printing that you need 
 24MP?
 
 Larry, Larry, Larry, LARRY!  Don't take the phun out of photography. :)

Don't be silly, the image quality of the gear has nothing to do with with the 
fun of photography.  However, taking a technical subject and beating on it 
until the dead horse is nothing but a smoking crater where a greasy spot used 
to be is half the fun of the PDML.

 
 I'm typically printing (having printed to be precise) at 20x30 inches.

In that case, I can certainly see why you would need a system with high 
resolution.  Especially if people are looking at your prints from three inches 
away.
 
 
 Also, what APS-C camera has that resolution?
 
 Sony SLT-A99, Sony NEX-7, Nikon D3200, Nikon D5200... not to mention
 the fabled Pentax K-3 is a 24MP APS-C sensor body, and Canon is
 looking at doing one if they haven't already.

And going by DxOmarks, or pretty much any other reliable test, how many of them 
actually outperform the K5 ( or II or IIs) in terms of image quality?

 
 Historically on this list and many others, when 'OUR' camera
 manufacturer's offerings have been surpassed by a competitor, a
 commonly expressed attitude is 'Why would anyone need that? I'm
 perfectly happy with what I have and need nothing more'. The persons
 'whining' for more are labeled as complainers. Then when 'OUR' camera
 manufacturer releases a new product that has essentially those same
 characteristics, many jump on the bandwagon and proclaim it as the
 best ever and how it beats the pants off the prior model. It's
 dichotomous to say the least.

My question wasn't entirely rhetorical.   I suppose I could have saved the 
lives of a few thousand wasted electrons by simply asking what benefit does a 
sensor that outresolves most lenses, and almost every display method I use gain 
me, especially at the expense of performance in areas where I am frequently 
running up against the limits of the camera?

And, for what it's worth, last night in order to get the shutter speed I wanted 
at f/1.8, I had to push the ISO to the 8,000-16,000 range.  
 
 
 In other words, with an AA filter, a 24MP APS-C lens will definitely be 
 diffraction limited by f/8.0. Without an AA filter, assuming
 
 that the lens is sharp enough, diffraction is probably having an effect by 
 f/4 or f/5.6.
 
 4um is 250/mm, which I understand works out to 125 lp/mm.
 
 I understand what you've written, yet nevertheless, an increase in
 resolution is just that, and it's visible at larger sizes more readily
 than smaller.  Also one can crop more easily and still maintain
 sufficient resolution.

That's interesting.  I suppose it is something that needs to be experienced in 
person.  Wasn't there a test recently where they took two cameras, one much 
higher resolution than the other, made a couple of 16x20 prints and even the 
most casual observer was able to tell the difference between them?  Anybody 
have a link to that?

I guess that sensors that outresolve the lenses improve the quality of 
photographs in the same way that oxygen free 4guage cables improve the sound 
quality of home stereos.
/jocular sarcasm

 
 Noise? Smaller pixels seem to mean more noise, but it then again it
 seems that manufacturers continue to beat that noise down, and
 therefore today we have cameras (not all) with the highest MP
 resolution ever and very low if not lowest noise. In addition, extreme
 high ISO shooting is not the one and only holy grail. Many photographs
 are taken at ISO's where noise is not a factor, and therefore the
 increased resolution benefits each of those images (unless maybe your
 shooting a beauty pageant). :)

But what about frames per second?  How can you live without a camera that 
photographs at 24 frames per second?

I certainly don't say that low ISO noise is the only thing that matters.  I am 
saying that it, and dynamic range, are what I run up against the most often in 
terms of sensor performance limits.

 
 snipped for size
 
 It seems as if you want a sensor that has approximately twice the resolution 
 of a very good prime lens, which correlates roughly with the Nyquist rate, 
 which would mean that you would never need an anti-aliasing filter, because 
 even without getting into diffraction limiting, you're already past the 
 Nyquist rate.
 
 Is this why you feel that 24 MP is so necessary in an APS sensor camera?
 
 The reason I feel it's necessary for Pentax (not every person who owns
 a camera) is because they'll get slaughtered in the marketplace if
 they don't. What if Pentax decided they didn't need to go beyond 6MP
 when other mfrs. were pursuing 8, 10, 12? Who goes out and buys a
 brand new 6MP DLSR these days?

This is where we are getting to the core of the matter.  Marketing.  It's 
easier to sell simple, easy to understand numbers. Particularly to people that

Re: How do I determine the resolution---dpi---of an image?

2012-12-09 Thread Brian Walters

Quoting Mark Roberts postmas...@robertstech.com:


Eric Weir wrote:


I've had a request that I send an image that's at least 300 dpi.
I have an image shot at 1/180 at ISO 400.


Uh oh. This sounds like a request from someone who doesn't know what
they're talking about.



Yeah.  I regularly get requests from people to use some of my  
wildflower photos in a printed publication and they will almost  
invariably say a resolution of 300dpi will be good.


As others have said, any image can be 300 dpi but, depending on the  
pixel dimensions of the image, the final printed size can be very  
small or very large.


A 6 MP image (3000 x 2000 pixels) will produce an image of about 10in  
x 6.7in (3000/300 x 2000/300).  But if the image is resized to 1500 x  
1000 pixels, the print will be about 5in x 3.3in (1500/300 x 1000/300)  
at 300dpi.


So, what I usually do is ask what size (approximately) are they aiming  
to print.  Then I can work back to find what resizing of the original  
image is needed to produce that printed size at 300dpi.




Cheers

Output resolution (which is in pixels per inch,

not dots per inch) is independent of image dimensions (in pixels). You
need to ask them for either the pixel dimensions they want (which they
probably won't know) of what their intended print size is (in inches
or centimeters).


I have LR 3. Is there a way in it to determine the resolution/dpi ---
I'm assuming they are equivalent---of an image? Is there a way to
control the resolution/dpi when exporting the image?


You can control everything in the Export dialog. The parts of the
Export dialog are as follows (scrolling from top to bottom):

* Export location
* File Naming
* Video
* File settings (file format, color space, bit depth, etc.)
* Image sizing
* Sharpening
* Metadata
* Watermarking
* Post-processing

The first two items are at your own discretion. The third is
non-applicable.

File settings should, unless the recipient specifies otherwise, be
JPEG file format, sRGB color space, high quality (how high is up to
you)

Image sizing is where you set parameters for the pixel dimensions of
your exported image. You know that the output resolution needs to be
300 ppi (though it really doesn't matter - the recipient can change it
to any value they like) but you don't know what actual dimensions in
pixels or inches are required. This is the information you need to get
from the person you're sending the image to.

(I'd leave sharpening off and skip the Metadata, Watermarking and
Post-processing sections for this.)

GESO - tango @ ISO-6400

2012-12-09 Thread Igor Roshchin

(Rick Womer, please stop reading now, or you might start hating me.)

I am continuing looking through the photos taken at the tango festival 
last weekend with the brand new K5 IIs.

Here are some 9 photos that were taken at ISO-6400:
http://42graphy.org/misc/ISO-6400-tango/
Most of them are not perfect: a few are slightly out of focus and/or  
are suffering from the camera shake (the camera was hand-held
for all these photos).
I was still playing with the settings (various AF modes) and modes
(S/TA/T priority).
But, I think these photos show the quality of the ISO-6400.
(Some NR, in the range 35-70 for luminance, was applied in LR, except 
for the 2nd shot, _IR00019, where no NR was done. For that shot, NO
image manipulation, except cropping and resizing was done, - hence some
noise can be seen).

And some of these photos are fun by themselves (IMHO).
Comments are (as always) welcome, including constructive critique and
recommendations.

Igor

Ok, I have a question for everyone

2012-12-09 Thread Christine Aguila
Hi Gang:

I just tried to send a test email which included a hot link to a photo located 
in my public folder
in my dropbox app.  The photo is given its own URL address, so there should be 
no problem,
right?

But there is a problem--it never posted successfully.  I just did a 2nd test 
without the link, and
that email posted successfully.

The other variable is that I'm doing all of this from my iPad, which is what I 
want to do, that is, 
I've been trying to figure out a way where I could 1) import photo via Apple 
card reader to
iPad (check: I have the adapter that allows me to do this), 2) render the RAW 
image (check:
I have plenty of photo apps that allow me to do this), 3) then upload photo to 
share via the 
web (here's the motivation for the dropbox test).

So do you think our PDML account is reading the dropbox link as some kind of 
spam and 
blocking it?

If dropbox doesn't work, I'll have to try another solution.  I'd really like to 
avoid flickr.  Any other 
options I should consider?

Cheers, Christine
