Yesterday, I was finally printing some color films that I had from the summer and I realized that some of them were not as nice as others. Those were the one that I left in the fridge for a longer time before doing a batch of C-41. So, it makes me wonder if the storage between exposure and development could be in cause.

So, what is considered a reasonable storage time between exposure and development for pro color film ? Is the fridge good enough or should they be frozen ?
