Eating a Klondike Ice Cream Bar and thinking...hmmm this ice cream is not solid, just stiff. Could it be the same with the Fujifilm FP-100c? I'm wondering... Think about it! You're a big company and want people to shoot up and use up the film you produce as fast as "they" can, and you do NOT want to give them any idea that they can buy a bunch and put them in the freezer for the next 2 decades, do you? Absolutely not!! No money in people buying something that can store that long. You want them to buy it and use it up near or soon after the "expiration" date so they can buy more.
The "photographers" already knew about the regular 35mm , 120, 220, 4X5 etc films being able to be frozen and the only hindrance there to longevity was gamma radiation that would eventually fog the film, hence fast speed film did and does not last as long in the freezer as say something in the 50, 100, 125 ASA range.
I for one am going to have to try this idea. If it works, you have film for the next 20-30 years.
