I've wondered about refrigeration & freezing of film. Isn't the humidity higher in the colder air? Will unopened 35mm cassettes keep out the higher humidity. I've been meaning to took up the formula for humidity & temp? Personally, I keep all my film in the veggie & meat bins @ the bottom of the reefer @ ~37F. For decades I've read that one should freeze film; one shoud not freeze it. I don't know. I'm assuming that that 37F is adequate.
I don't know of anyone who thinks that @ least it shoulden't be refergerated.
