I really did not put the right question. I'll try once more. I've
a panchromatic film (T200 200 ASA made by FOMA) and I want to remove
all dyes from it and then aply another one (neocyanine) to make it
sensitive to IR radiation. I've tried it without removing dyes, it
worked, but the sensitivity was lower than I expected. I would like to
try it without any interfering dyes. Does anybody know how to remove
them without destroing emulsion? Thank you.
