Simple example. you have ISO 100 film only. You have a low
light situation. set the ISO to a higher number.. say 400.
tell the lab that is what you did (that is, you shot the
film as if it were ISO 400). They will compensate in the
processing.
Different films react differently/perform more or less well
and there is plenty
of information around (which I dont have handy) on which
films are best for
pushing when necessary. YOu can "pull" too - shoot 400 at
100, etc. YOu just
always need to let the lab know what you did.
The results from pushing are almost always a lot grainier
than what ever you started
with but if it is the only way to get the shot with
available light you just do it.
