>From the perspective of image detail, I find little advantage to 4000
dpi over 2000 dpi with most films, but the big difference comes in
with the grain. The higher resolution scans help make the grain a bit
less in-yo-face.
My best B&W digitizing efforts, though, are when I make a quick 5x7
work print in the darkroom on the cheepest RC-Glossy paper I can find
and then flatbed scan it. Zero grain.
Multi-scanning negatives does help reduce the grain effect a bit on
the negs as it averages out the influences a bit, but the
multi-exposure setting doesn't help any.
