RE: filmscanners: Sprintscan 120 and new negative proile scheme



David,

That is what I believed you would say, and I completely disagree with that
philosophy.  Films have certain characteristics that photographers use
particular films for.  I don't want every film to give me the same results!
People never did this in the darkroom, so why do it in digital?

Just my opinion having been a professional photographer for 20+ years...
Also note, no one ever used film profiles for the Leafscan, which was one of
the most prolific high end scanner used for the past 10 years, nor did they
ever ask for them.  I don't know if they were ever used for any other
scanners, the SS4k was the first one I found that had them, and I didn't
like them.
