"Perhaps I don't understand the question. Both are (nominally) fast
panchromatic films; although the Polaroid was a color film, that
emulsion would be sensitive to all colors. Presumably there would be
some far infra-red light where they would not respond. Far infrared
is not convenient to view unless you have an IR detector."

Thanks, Peter, let me rephrase/ explain further....

I have a "portable darkroom" actually used to process x-ray films and I'd
like to be able to use it with either Polaroid 600 instant or Fuji fp-3000b
film. The darkroom's original purpose was to allow for fast processing of
dental x-ray b&w film. There is an amber cover that allows the processer to
see what occurs as the film is processed through the solutions. I was
asking if I could process the aforementioned (actually safely work with, not
process) the instant films in this portable darkroom, viewing through the
amber window, without either/ both of the instant films becoming exposed.

Thanks,
Deshawn
