Digital BW, The Print

Think about if you really need to scan a 4x5 neg at 4800 dpi. Are you
making billboard sized prints that people will view up close? Just
figure out what rez you need to scan 4x5 at to yeild your max print
size at 360 dpi. I bet you'll find that any scan more than 1200 dpi
gets downsized in the printer driver anyway. Then you have a
reasonable file size that you can work quickly and no impact on print
quality.
