I shot some Acros last weekend. I am using the 4990 and Silverfast Ai. I can scan it as a negative, 16 bit grayscale (and since there are no Fuji B&W film choices in the popup box, I selected Koday TMax). Then I scan. I assume this is the correct procedure to scan as a BW neg? If not, what should I do different?
I have been reading about people scanning B&W negs using only one color channel, red, blue or green. One is generally sharper than the others. I have no idea how to go about doing that. Set it up as a positive, not a negative, then convert it in PS? If it is a positive, how do I go about selecting a color channel to use? What control(s) in Silverfast should I use? No clue. Then once it scanned, use channel mixer to convert it to B&W? I normally use chrome for B&W and have used the channel mixer for my conversions, but this B&W stuff has me stumped.
Any tips would be greatly appreciated.
