Dear Sandy
Did you (or anybody else) try this process?
I did it years ago, following the brief description of Luis' carbon
book. As I remember, problem was the photographic paper.
I tried some ordinary baryta paper and a bromoil printing one.
Any ideas?
Thanks & Regards
Stefan

Gelabrom is essentially a variation of carbro. It is somewhat easier to
work in that one of the most critical procedures of carbro, that of
squeeging together the bromide with sensitized carbon tissue, is obviated
bt the fact that the tissue is made in situ on the bromide. A disadvantage
compared to carbro is that you are limited to the surface of the bromide
printer, i.e. no transfer to another surface is possible.
As in carbro the gelabrom the tonal scale is like the curve (S curve) of a
silver print, the bromide printer used to make the pigment print. This
makes it very different from a carbon print which has a very long straight
line curve.
