Hi Andras and Simon,

ALL CCD scanners that I know of, with the exception noted in the next
sentence, scan EVERYTHING in RGB, whether you select B&W/Monochrome or not.
The ONLY CCD scanner(s) I know of that scan B&W AS B&W, using a single ND
filter, is the Leafscan 45 and the Leafscan 35.

So, the point is, you ARE scanning the B&W film in RGB, just the scanner has
it's own "mix" of RGB that it uses to convert internal to the scanner and
then give you the monochrome image.  EXACT same thing that PS does when you
convert from RGB to B&W, but in PS, I believe you can change the "mix" of R
G and B.  I REALLY wish scanner manufacturers would make their
scanner/software so that you could change the mix there too...

Personally, I believe the Leaf gives much better B&W tonality than any other
CCD scanner I've ever used or seen.

Austin
