Epson 2450 - negs on glass [was:Re: Scanning Tri-X]

2004-01-09 by Mark Hahn

isn't that a little contradictory?  I mean considering film flatness 
a benifit on one hand but then deciding that DOF covers all focus 
issues... :)

with 4x5" I don't worry about getting my film at the sweet spot 
either, but for 35mm it would be manditory and even with MF I think 
it makes some real difference in the results.  Skill in sharpening is 
important, but it doesn't change the quality of the starting image, 
and that is important... sharpening will not *fix* blurry images.
