When I was out on Sunday morning it was pretty dim to begin the day requiring high ISO and slower shutter speeds. I shoot Auto ISO, which I like now on the D200 as well, and as you can see from my other images in the Bird gallery the ISO's varied. These were some from early on, ISO 1600 in the real world. 1.25 stops underexposed, at least. I applies a light touch of Noise Ninja, just the defaults. 1 stop underexposed, no additional noise processing. Exposed much better, no additional noise processing. Scientific? No way, but these are "real world" as the world was on Sunday morning. I don't think they are too awfully bad, what do you all think?
