beautiful. just think how much nicer it would have looked if shot with a
canon.

No flash.

It is GREAT. From my heart. I like Foveron CCD also, but if they could
provide a CCD with more pixels, it will buy it.
Since more pixels can let me crop the photos, but only 3M is ready not
enough, but it is not related to quality.

This is about the best you'll ever see from the super low
dynamic range Canon 10D in sunlight...

Yes, it is the best you can get from a 4th rank amateur (calls him self a
pro ;-)) as he overexposed his shot so much that there is virtually no
detail in the 18 darkest histogram bins. At least he got the skin color
right, oh wait, it's the camera that got it right.

you're funnier than me. but seriously, as lovely as that sigma shot is i
couldn't help but notice how pixilated the edge of rock in the fore ground
looks and the purple fringing of it against the distant background and that
it has some hot spots that gives the entire image that phony/flat/digital
look. referring to the 'original size' image where detail is not hidden.

I like how he softened the image and mucked up the contrast to make his
point.

That single image gallery looks like a suspicious to me. And where's
the exif data showing that this was shot with a 10D? Maybe it's
missing because you just degraded the original image and posted it in
a sockpuppet gallery.

I like Mikes work, he brings back lots of great memories for me as at one
time or other, I think I've been to most of places he does such a great job
of capturing digitally. I really like what he does composition wise. He gets
great results.

That said, I think Steves comments regarding this particular photo and
dynamic range shows more about SG's lack of understanding and experience
with dynamic range than it does anything else. I quickly scanned back over
hundreds of my old shots from the same general area, and find that even my
old Toshiba M-70 for the most part had a slightly wider dynamic range in
similar situations, even though it doesn't have RAW capabiltiy You need to
capture the same scene at the same time to be really sure. In this
particular photo, while there is detail in the shadow areas, there is also a
very noticable color shift, which to me says the camera wasn't really able
to capture the shadow detail fully. Not knowing exactly how the photo was
post processed makes it hard to say what was possible with this shot, but to
me it shows somewhat a lack of range if anything, and looks like the shadow
area was already boosted about as much as is possible either by a curve or
"fill" flash type function in the post processing.

As for the SD9, I would be interested in seeing any independent tests that
show the Sigma has a wider dynamic range than any Canon or Nikon DSLR used
in the RAW mode. When the SD9 first came out, I was quite excited by the new
technology. I actually took the time to get my hands on one and do some side
by side with a D-Rebel and the sigma. With both cameras in RAW, captureing
the same scene, I found the canon had slightly wider dynamic range every
time. I find it interesting to read all the opinions regarding camera
dynamic range, as they seem to be all over the place. Seems kind of strange
being as how it's one of those things that can be measured and compared. As
for the blown highlights steve keeps refering too, that's a function of
camera metering/the user. Whether or not the camera captures the scene
optimally to where you can process for the widest possible dynamic range is
another story, but obviously if your exposure is off a stop or two, you're
going to loose out on the other end by the same amount.

For what it's worth

So the 10D can't take a picture in normal sunlight without blowing the
highlights huge. It's 1990's vintage Canon CMOS has lower dynamic
range than any decent CCD based P&S, which is truly abysmal for a
DSLR. This is about the best you'll ever see from the super low
dynamic range Canon 10D in sunlight...

Jesus Christ...what do you want? Film can't capture that much of a
dynamic range. That's a 128:1 lighting ratio.
