My rules of thumb for cold stored 35mm film have stayed the same since roughly 1988: If the film is stored in the fridge, let it warm up for an hour before loading in the camera (I have reduced this to 1/2 hour if I'm impatient with no ill effects). I've never really stored it in the freezer, but have some Rollei IR 400 in the freezer now and will probably let it warm up 3-4 hours if not overnight before loading it.
