Hypothetically, if I were to buy the Goldeneye print, how should I store it?
The best way is to freeze it using the CMI packaging method. NASA freezes their Apollo footage, for example, but they have precise humidity controlled cold archive chambers that are unattainable for most archives let alone every day folk like you and me. But the CMI method allows you to use household freezers and commonly available supplies to safely freeze and preserve film.
I have a 16mm Disney archive and preserve my prints this way. Colder is better to prevent color fade for all prints and backing degradation for acetate or nitrate prints, but unlike undeveloped film that isn’t sensitive to relative humidity, developed film sure is. 20-40% RH is the range, 20% being ideal. You basically bag the print with two pieces of dried mat board, and bag it again and throw it in the freezer along with a relative humidity indicator card.
If you don’t have a freezer that large, you could use a fridge. Failing that, the next best thing to do is keep them cool and dry. Use vented film cans like these (http://urbanskifilm.com/supplies.html) or drill holes in the cans you have. Modern prints like Goldeneye are almost certainly mylar/polyester backing and don’t suffer from vinegar syndrome or catch on fire like nitrate, but high temp/humidity will accelerate color fading regardless.
Feel free to PM me if you want to talk more.
Thanks! Luckily, I haven’t had to worry about this, as the print is now in excellent hands and will be taken good care of 😃
