    Storing Negatives

    What precautions do I have to take for doing this? I keep all my negs, colour & mono in plastic sleeves. What sort of temperature and humidity are ideal? Any other conditions I need to keep an eye on?

    Thanks

    Alex

    Keep them in a dark area. Slows down fading or something…

    Wilhelm Imaging Research has got an interesting book talking about everything archival: http://www.wilhelm-research.com/book_toc.html
    Chapter 16 talks about the environmental conditions.

    Overall it's about keeping temperature low (lowest as possible, much better for color; B&W doesn't care that much), Humidity between 30-50% and dark. Also away from pollution.

    So what about keeping exposed negs in some sort of cool box?

    I, my equipment and negatives were relegated to the basement a long time ago. Our basement is pretty dry as basements go, the humidity is between 35-55% (winter vs. summer) and the temp. between 65-70, which is pretty much the comfort range for us humans as well. Some of my negatives are more than 40 years old and are fine.
    WYSIWYG - At least that's my goal.

    Ah but this is only because your basement had quite favorable conditions. 30-60% humidity is not common in basements at all. Even my garage stabilizes between 50-80 depending on season and daily weather.

    Highly valued negatives should be relatively air sealed and frozen. A vacuum seal is not necessary but cold temperatures and the implicitly low humidity of a freezer are quite a big advantage.
    Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
