I'm building a cryogenic vault that will keep my film at 1.5k and shield it from all known radiation. This should extend it's storage life by billions and billions of years.
This seems to be one of those eternal questions, similar to the "is the .30/30 adequate for deer?" debate. The answer is, yes, you can move your film from the refrigerator to the freezer, from the freezer to the refrigerator, from the refrigerator to the basement, from the basement to the coffee table in the livingrooom, from the coffee table to the freezer, from the freezer to the patio, from the patio to the garage.
Just make sure condensation cannot form on the film. It really is that simple. And don't thaw it in the microwave.
