Good question. I think the most fair answer is I simply don't know. I've
never stored film, frozen or otherwise, appreciably beyond the marked
expiration date. Since I shoot color negative 990f the time, a proper
critical evaluation is hardly possible.
What I have noticed is when I print a number of enlargements from the same
film emulsion lot, I have far fewer rejects. Now mind you, I still fill up
the trash can, but my batting average improves greatly. There are so many
other variables I like to kid myself I have some semblence of control over -
exposure time, processing step timing, color filtration - to name a few of
the major ones. Mixed film types and lots make this all the more difficult.
Since I am messing with so many variables other than film storage
conditions, I can't honestly say much about a color difference in the film.
What I have observed is a level of repeatability in making prints with the
same batch of paper stored in a freezer and properly thawed (tightly wrapped
in the original packaging until warmed to room temp) over time. I can
reproduce the enlarger setup and processing steps from my notes and the
second print is usually right on.
What I should do is an experiment with some slide film. Then the only
difference left to evaluate is the storage conditions of the film.
