Re: filmscanners: Vuescan - A few technical questions
I don't know, but that's why I suggested perhaps Ed would answer the
question as to what mechanism is involved - a color or gamma shift, e.g. -
so that we can use the option appropriately.
Hopefully we will hear from him tomorrow, and meanwhile when I have time
I'll check the file and maybe 'reverse engineer' the Restore Color function.
