if you have phil Hart's shooting stars e-book he has a very good chart of a canon camera whereby he took a series of shots from iso100-3200 [maybe 6400 i forget] when he works the file in curves & strecthes them -they come out looking nearly identical. there were 1 or 2 iso's which look slightly better -iso i think is just a digital gain setting in a non-film based system
he also has a good noise explanation relating to filling buckets of water
