I worked in a camera store in the 1970's. The reason for professional films that needed refrigeration was to be able to match colors like the red in Coca Cola ads. Professional films were just like amateur films except they were ripened to a set point and refrigerated so as to produce the same colors from batch to batch. Amateur films were sent out less ripe based on an estimate by Kodak of how long it would take to ship and how long the average roll would sit on the dealers shelf.

I've heard similar stuff about the red that Coca Cola uses, but also has a patent on it (???) so that no one would be even allowed to copy it. Can anyone verify this?
