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.
