Storage of Unprocessed Film
Posted 07 December 2011 - 01:26 PM
Sorry about posting but the search function on this site is lacking.
I shot three 100ft. rolls of Kodak last week. They are now in my fridge (not freezer). I just read that if stored, it should be at 0 temp.
I was going to just leave it in the fridge until I can make time to send it out (next week). Is my film going to suffer any lose since if
undeveloped and only in the fridge? If I put it right in the freezer from now until developing should it be okay? I'm not home otherwise
I'd do it right now.. What happens to the film otherwise? Fade in colors? Its two rolls of 250D, one of which I will be pulling a stop, and one
roll of 500T, both Vision 3. Any advice or information learned from experience is appreciated. Thank you.

Next time don't bother for as short a period as a few weeks.
Whatever you do now, don't put it in the freezer; the fresh stock was packed in dry conditions and any water vapour introduced since the seal was broken might be frozen onto the film. Defrosting then would be disastrous.

What about unexposed film? Can it be stored in the freezer until use or fridge?
Fridge is always safe, as long as the film is well sealed against humidity. and has not picked up moisture from use.
I have seen Yeas and Nays about using the freezer. Film should only be frozen if it is still in the factory sealed package to avoid frost effects. I have seen some posts that implied that "some" films "don't like" being frozen. Only data sheet I have seen that says to store at 4C is from FOMA (http://foma.cz/ )

I put the film in a plastic bag just incase. I think I'll use the fridge from now on.

The latent image is best preserved at cool temperatures is not processed for more than a week or so. The cooler the temperature the better and freezing an exposed roll for much later processing is done routinely and safely if the warm-up is done properly.
Some stocks such as Agfa CP30 don't support freezing because some internal crystals break (simplified explanation).
If you have ever seen the documentary 'March of the Pinguins' you will understand that modern film is quite rugged as well as the Aaton S16 cameras that were used to film it. If shooting in arctic conditions, you want to leave the camera and stock outside all the time (protected of course).

back in the fridge so, it spent a couple days in the freezer, hopefully moisture did not build up. It
will now get a day or two in the fridge so I'm hoping that time will be enough for it to adjust before
bringing it back into room temperature.
So we do all of these things as a precaution but I'm still curious about what negative effects might occur from
ignoring all the do's and don'ts of proper film storage. Some kind of fogging? Loss of certain colors? Saturation?
Overall brightness? Overdevelopment? Underdevelopment? Just wondering.. Thanks again.
