Are you saying this applies when using Vuescan - especially with negs?  Or
are you assuming the sort of interface that Nikonscan provides?

OK, then I think we agree?  Other than what you mean by "raw data".  I
wouldn't ever attempt to use an editor (I don't own PS by the way) to do
what Vuescan does to go from the raw scanner output from a neg to produce a
positive image.
