The chemical reaction that developes the picture is temperature
sensitive,
like many chemical reactions. In cold temperatures, a longer developing
time may be required, or you could put the picture 'sandwich' someplace
warm to develope. Early Polaroid instructions suggested putting it under
your arm, and included a metal holder for warming.


Question: As I understand it, using this film (Fujifilm FP-100b),
this process is begun once the pic has been pulled out through the
rollers,
which then 'squish' the developer stuff and spread it over the pic. My
question is: How long is it recommended to wait until actually starting
this
process by pulling the tab out? I'm not talking days or even hours, rather
only several mins.

Since the developing process has not yet begun, seems to me you
should be able to keep the pic there for some time without any damage, nu?


The light hitting the film also causes a chemical reaction, albeit a very
weak one. The longer developing is delayed, the more the effect of that
delay will be. I suspect that minutes, perhaps even hours will have little
effect. Just for fun, why not take a shot, pull it out and develope it, then
take another shot and leave it in the pack for a day or two.
