[filmscanners] RE: Difficult scan problem



Tony,

Your response covers the negative aspect and for that I would be inclined to
accept your inclination; however, I think the problem arises from trying to
digitalize via scanner what colors the film has captured in its gamut so as
to reproduce it digitally in a color gamut that can be presented on a
monitor display or digital inkjet or other type of digital print. Just as
there are differences in what negative films can capture versus transparency
films, there may be a significant difference in what film  and traditional
photographic prints can capture in terms of color and digital color spaces
can handle.  Just some speculative mental masturbation. :-)

Hmm. I'm sure you're right, in a thoroughgoing, theoretical sense. My
inclination would just be to suck it and see what you can get out the end
of the process, given that there's not much which escapes modern colour
neg, although there are bound to be minor changes and distortions of hue.
