    Film storage

    What is the best way to store colour film?
    I have always used a fridge. I now have so much film it is starting to fill my walk in freezer. I have put it all in zip lock bags. The freezer is at -15. Am i storing it correctly?

    I do the same: I buy all my film in bulk (100+ rolls per order), and package each brick in a suitably-sized Zip-lock. I have yet to have any issues. My freezer to use time is one day (erring on the side of caution is my policy). Once removed from freezer to use I generally don't refreeze;the unused portion of the brick in moved to the refrigerator (not sure if this is necessary, but, once again, caution to avoid potential problems - real or imagined).

    As far as I know, keep it frozen. What ever you take out, put the rest back in the freezer. It's not meat, so it's OK. I have some of my Dad's Minox film from 1987, and it's still fine!

    For all practical purposes, they've taken Kodak away.

    You have a walk-in freezer?

    A walk-in freezer!?
    Long term storage of film in a deep freeze can induce embrittlement of the emulsion. Among other risks, when the film is released from the chilled environment, moisture can build up and mottle the emulsion. You really need to store it carefully and conscientiously and allow it the time to acclimatise to ambient temperatures. I store my own film at –20°C for long term (acknowledging the risks I mentioned) and at normal fridge temperature for short-term, go-to use.

    i always allow a few hours to defrost before use. I then re-freeze what i don't use.

    p.s. i could only imagine my freezer being full of film...

    I've heard him say it in the past but I've never heard of a case of brittle film nor experienced it myself with film (e6, b+w)that has been frozen for 20+ years. I'm sure there are exceptions but........where?

    You may want to use recyclable bags of desiccant inside the moisture-tight wrapping when you first wrap the film, and allow enough time to thoroughly dry the film inside BEFORE you either freeze it or refrigerate it. Similarly, when you remove the wrapped film from refrigeration, allow plenty of time (at least several hours) for the wrapping and film to come to room temperature before unwrapping. Without desiccant you run a double-risk of ice or moisture on the film both when freezing and thawing. I've tried freezing, but I found a 50-deg cool location the best, mostly from a convenience point-of-view, and no problems with moderately out-of-date film. Very long-term storage of film and paper might demand freezing. Military-surplus stores sometimes have inexpensive recyclable silica-type desiccant bags.
