Re: Use of scanner for EM B&W Negatives

From:Roger Moretz

Caveats first:  if you are going to scan EM negatives,
be sure that the density range of the scanner is at
least 3.4, higher if possible.  EM negatives have such
a wide range that I think that it is possible to lose
data this way.  Second--setting up to print out 8x10
prints so that you aren't tossing many poor prints, or
aren't spending a huge amount of time attempting to do
some contrast adjustments, etc is not trivial. 
Printing from digital originals is relatively straight
forward.  But my experience (somewhat limited and done
under pressure) was not good.  Not enough time to set
the system up first before having to produce results
for a study....  All in all, not a terribly good
experience.  Maybe others have had better experiences.
