Does Kodak Portra film need refrigeration after it is exposed?

I will be using the film about 250 miles from home and I will not be
returning home for two days after it is exposed.

 

No. It can easily go a few days or even a few weeks without refrigeration.
The refrigeration is to keep it from aging during the 6 to 12 months from
the time it leaves the factory until you finally use and develop it.

 

No. Storing a film in a refrigerator just slows down the ageing
process of film. Storing a film in a freezer keeps it looking the
same even longer.
Days, weeks, even a few months at room temperature will not change a
film that much. The only thing that can really damage film is heat.
Don't leave your film locked in your car with the windows closed in
the summertime, don't store it on a hot water radiator or in the
window of your hotel room and you will have no problem.

 

Put in original canisters. Wrap in big fluffy towel. Bury in trunk of car.
Don't worry about it.

 

No, as long as you keep it near room temperature and not in a car's
glove compartment.

 

Wasn't it hba1c who said...

No. In fact, once the film has been unsealed from its canister
(or original packaging, in the case of roll film) I would advise
that you DON'T refrigerate it.

When film is warmed to the ambient temperature after being
refrigerated, it is subject to surface condensation which would
dry on the film potentially leaving residue which would mar the
surface. This is why you only refrigerate film in its sealed
packaging, and wait until the film warms to the temperature of
the surrounding environment before breaking that seal.

If you were to refrigerate the film, unsealed, after it was
exposed, you would subject the film to the effects of
condensation once again.

Only refrigerate film before use, and only in its original
factory 'air'.

 

I did a wedding in Bali a couple of years ago, the average temp was 35 deg C
with a humidity close to 100%, the portra had no issues at all and printed
up great on my return to Australia a week later.

 

If you return exposed film to it's air-tight container and refrigerate
it, and then later allow it to warm *without opening the container*,
there will be no condensation. Condensation forms when relatively warm
and moist air touches a colder surface. So long as the film and the
trapped air are allowed to warm up together in the sealed plastic can,
no relatively cold surface is available to condense on.

If you refrigerate unused film, and then yank it from your fridge and
slap it in your camera, you risk instant condensation. All refrigerated
film should be allowed to warm in it's sealed container.

Finally, exposed film is more sensitive to heat than unexposed film.
That latent image will fade with time/heat. A few days is nothing to
worry about. If it's going to be weeks (African safari?) refridgeration
would be a good idea.
