Ned,
The b/w films I've been scanning with Vuescan (and a Canon FS4000) are TMax
100, Ilford FP4+ and Portra400BW. What I found is that Vuescan cropped (i.e.
processed) files are beautiful with TMax, using it's own profile in the film
selection list, but with both FP4+ and Portra I get better result starting
from the raw file and extracting the green channel (which has the best
detail and the least noise on most scanners - YMMV). I have a simple
Photoshop action that opens a raw file, inverts it, calls Channel mixer
picking the green channel, and finally sets the image mode to Grayscale. It
takes about forever on my old PentiumIII, but I scan a few frames and then
let it run in batch mode for half an hour.
Hope this may help.

Subject: [filmscanners] Problems scanning Porta 400 BW with SS4000/Vuescan
Hi all
Attempting to scan in some Kodak Port 400 B&W film with my SS4000 and
Vuescan 7.4.2 and getting really poor scans.
When I view the raw output file I can see that it is black & bright red
rather than black & white (ish)
the filmbase is quite reddish, like normal colour negatives.
anybody got any suggestions?
regards
ned
