i am surprised you did not get more digital noise with the d100 shooting at 1600, your exposure must have been spot on without much lightening necessary. My D1 gets awful above 400, I usually try to only shoot at 200 if possible. I was just issued a D1x and this seems to be a lot better. it amazes me how fast technology moves. You might try adding a bit of red to this image in the shadows and midtones, i think I detect a hint of cyan or green. really nice work
