Let me elaborate on that.  The Leafscan 45 (and the 35) scan B&W as
grayscale.  Every other scanner scans B&W as RGB.  There are issues with
scanning in RGB with a CCD scanner, in that the channels all have different
levels of sharpness.  The red being the fuzziest, blue next and green least.
It's not just as simple as saying use the green channel, because you can
lose tonal information that way.  Most scanners have a canned mix of how
much from each channel they use to "make" grayscale.  Some people keep their
B&W scans in RGB and do the mix in PhotoShop, and as a note, PS has a canned
mix as well for it's convert to grayscale command.

Anyway, I believe it is because my scanner scans grayscale using a single
channel with a neutral density filter that I don't have to sharpen.
