No, its not another "film is dead" thread, well, maybe a little :-)
As many have done already, for various reasons, I am curious about stockpiling film in a deep freeze. Since film is relatively small in size, an inexpensive deep chest freezer can hold a ton of film. This is not only a final defense against a paticular emulsion being discontinued, but also a general question as many of us have film sitting in the freezer that is 5 years old.
From my experience, I have never had any issues with Fuji film in a deep freeze for 5 years. I know film makers date film for about one year from date of manufacture, but it seems it's life is so much longer then this. Just how well does deep freezing the film add life to the film? Is 10 - 15 years unreasonable? What temp is ideal, whereas lower temperatures offer no more benefit? When film is effected by age, how does it surface in the exposed image? Is it mostly color shifts or speed losses? I have never found any good references for this issue?
