Hi.

Do you know of time adjustments with pushed or pulled film, the reciprocity failure?

E.g. if I pull 320 film to 100, how does it affect reciprocity failure times?

Thank you
 
I don't know of any still-available instant films that can be pushed or pulled. The FP3000b could be contrast adjusted slightly by peeling early or letting it stand extra time, but that film has been out of production for around fifteen years. Integral films are self-regulating, within their temperature limits.
