I get that high ISO increases noise (especially in black areas). Most people even shoot with an increase in exposure compensation to help avoid shadowy area (rather than just balancing exposure because of what's in the scene) but not too much to blow highlights out really bad. Doesn't raising your exposure comp justchange one of your settings (A/S/ISO speeds)? If your in a dark place where you are already playing with your limits (100mm lens @F4 set to ISO800 with 1/75sec shutter speed, how is adjusting the comp going to keep down high ISO noise in the shadows? The Ex.comp is going to want to make it brighter by adjusting something which might lead to a softer, blurry, or noisy picture. I read this thing twice and it makes more sense in my head than in writing. If you understood it, help me out. I know I'm missing sumthung.
