did we lose the discussion about over exposure?

also, with hi iso you DO NOT HAVE THE SAME range to mess with an image as you do one shot at a low iso - for those that think the same rules apply when shooting high iso, or that think you can pull a lot of data out of a high iso file, raw or other, particularly of animals or humans, I'd suggest you go shoot at 1600 or more and look at your results. . . the point is you must nail the exposure when shooting high iso or the image will suffer greatly from PP, much more than if it were shot at a low iso and processed the same. . .
