A lot has been said about prolonging the life of film by freezing it or putting it in the fridge, but what about colour processing chemicals? I am thinking of E6 reversal in particular. I use a bit of E6 film but would use more if I could buy a kit to do it myself. Opened bottles of the chemicals have a limited shelf life because they absorb oxygen and 'go off', but if they were deep frozen how would they be able to absorb anything, so prolonging their shelf life. I am not talking about part used dilutions here, I always use once and throw away, it is just the part empty bottles of concentrate. What are the views on this?
