We don't always complete a roll of film soon after it's loaded,
and sometimes the film, both exposed frames and unexposed
frames, is kept in the camera for quite a while. A few times
recently the term "hold time" has been used to describe the
ability of a film to hold a good image after exposure. This
time, I'm sure, varies with the emulsion and the conditions in
which it's stored. So, my questions are these:
Where does one find information about the "hold time" of a
particular emulsion?
Wouldn't refrigeration or freezing extend that time?
If a roll of film is refrigerated or frozen, removed, allowed to
cool, and then placed back in the refrigerator or freezer
(because it wasn't used), can it suffer an ill effects? Can
this process be repeated more than once, also without ill
effects?
If a roll of film has been partially exposed, placed in the
refrigerator or freezer for a time, and then removed to shoot
the remaining frames, can there be any ill effects, especially
on the captured images? Can this process be repeated several
times?
What about condensation? If film is refrigerated or frozen
while in its original, sealed container or package, condensation
should not be a problem. But once warmed, and the package seal
is opened, would replacing the film into cold storage allow for
any condensation on the emulsion? How much of a problem might
this be when the film is removed, warmed, and run through the
camera again to complete the roll?
