Digital BW, The Print

8in x 10 in.  Let's say we want 360dpi to be sent to the printer then you
need 2880x3600dpi.  You are scanning 4x5in negs.  So you need only scan at
2880/4 dpi or 720dpi.

BUT who knows whether you might like one of those images printed larger -
even if you have to outsource it.  Rule:  scan at the best optical
resolution of your scanner and tuck the file away.  If computing constraints
are making work too cumbersome then copy this file and down-res it to 720dpi
for your 8x10s.
