My only complaint with my Nikon LS-4000 is that it really seems to
emphasize the grain in my fast films (Delta 3200, Fuji 1600).  It's
bad enough that I consider it a problem, but for now I've just been
contenting myself with a "going for the grainy look" attitude.  If
it's important, I rescan it on my LeafScan45.

I've heard explanations that the effect is caused by an unfortunate
confluence of the small light source (led?) that Nikon uses, along
with an aliasing interaction between the film grain and the 4000 spi
sampling rate.

I've read that scanners at a higher resolution don't have as much
trouble with aliasing of b&w film grain, and that scanners that use a
diffuse light source also make less of it.  Both of these observations
run true w/ the results from my Leaf.

Hopefully you've also figured out that Nikon's automagic
dust-n-scratches stuff doesn't work with silver-based B&W films
(although it does work w/ the chromogenic varieties).
