Hmm.. thanks.. maybe I need to reset my expectations when it comes to
film scanning.
Does anyone have any recommendations as to a web resource I could use
to learn about histograms? I understand a little bit, and can tell
when highlights are clipping or I'm losing information with gaps in
the histogram but if there's a good resource out there on histograms
and adjusting "levels", and what it all actually represents and the
theory behind it, that would be very interesting.
