What are the advantages of freezing film?
How can I tell if film is too old to be used? How long does film on a throwaway camera last?

There is only one advantage to freezing film and that is to slow down the aging process. Most camera film will maintain the film speed for a period of at least two years from manufacture. Freezing the film will slow down or even stop the oxidation of the emulsion layers, which is what causes film to get out of date. The danger in freezing is moisture. If moisture gets into the film it can ruin it. If you are freezing film it is best to but the film in a vacuum-sealed bag. When defrosting the film let it warm up gradually. Take it from the freezer and place it in a cool dark place for a few days before trying to use it.
The film may still record an image even if it I old. So for example if the film is very old but has been frozen then try using a lower ISO setting by at least ½ stop. If the film was ISO 200 try shooting it at a setting of ISO 100 to compensate for the loss in speed.
