Sure thing! I'm getting my wisdom teeth out this morning though, so it will be a while.

RawTherapee is the best program for it, I think. I think the "neutral" profile would work out of the box.

On Canon bodies it certainly will. I'll compare the same exposure when ISO is set to both 100 and 6400.
