Ok - here's one that has just received minor sharpening (what I would do for any shot coming in at ISO 200)
And here's another that I've tried my hardest to "fixup" with sharpening and NR:
Last night when I posted I had my MacBook Pro on my lap. I actually hate evaluating images on my MacBook screen because of the contrast and saturation, and the fact that the brightness is all over the place based on where I'm sitting.
This morning I took a 2nd look on my 23" HD monitor which is calibrated in all respects for photography and printing. Not just color, but brightness, contrast, and saturation are set to match printed output from my 3880 as closely as possible. Another important difference: I think last night I just clicked the image and used Preview. This morning, PS CS4. Screen view quality depends a lot on the scaling algorithm used by the viewing program, and a lot of programs produce scaled views which are grainier and softer than PS. Apple's Preview can be particularly bad with high resolution images scaled to certain sizes.
Looking at the first link...
* At 50% (22" print size on my screen) there is no noise visible, period.
* At 66% (36" print size) detail seems a bit rough, but there is no real noise to speak of.
* At 100% (54" print size) there is visible noise in some areas. But if you have any kind of film background, it's far less than the best 35mm films ever were, and even less than MF films printed this size. (Of course MF film would have much more detail at this size.)
Forget what I said last night that it seemed to have more noise then I would expect. Viewed in PS on a properly calibrated monitor it's fine. Exposing to the right would have helped with the noise at pixel peeping views, but made no real difference in print. The lens issues (CA and some softness on one side) stand out far more and at smaller sizes than any noise.
FYI, a standard Noise Ninja pass using their 7D ISO 200 profile eliminates pretty much all of what you see even at 100%. At that point you have to zoom to 200% (108" print) to see noise.
And this is all after you sharpened. If I use Noise Ninja, I use it before I apply local contrast enhancement and sharpening.
I trust PS scaling and my monitor 100%. What I see is what comes off my printer.
So how are you viewing and evaluating this?
