This is confirmed, and further it cannot be developed to a negative in
conventional B&W processing due to a colloidal silver antihalation
layer. The only practical way I know of to get a negative from Fomapan
R is to develop in a color developer with the same black dye couplers
used in XP2 or BW400CN type C-41 B&W films, then bleach and fix as for
C-41. For B&W positives, of course, you use the regular first dev,
non-halogenating bleach, reversal exposure, second dev, fix process that
would produce a positive on any B&W material -- but the bleach step is
mandatory to remove the silver AH layer.

Anyway Fomapan R is cool stuff.


Indeed - good sharpness and grain, nice tone, and stunning latitude
for a slide film.

Never tried it, but I might have to get a short roll and try it in my
Minolta 16 cameras once I have the resources to do reversal processing
-- using Diafine for a first dev should give EI 160 to 200, and grain
would be determined by the second dev, which could be a super-fine grain
soup like Microdol-X or Ilfosol.
