It has to do, I think, with whether you wish to neutralize or retain the specific spectral characteristics of the film you're shooting with. Time was, when one's choice of film (well, at least slide film) was predicated on a preference for a particular color balance, saturation, etc. But with a digital back end, so much of that can be added in (or removed) later on, so I sort of wonder how this whole situation is changing. With color negative film, the situation gets even more vague, of course, since there's almost no objective way to characterize the colors in the negative itself. rafe b. - Turn off HTML mail features.
