Hi everyone. I'm really new to vintage film photography and just starting out with my first small collection of unmounted negatives & transparencies from the late '60s/early '70s. I have no idea how to store them so that is my main concern - to keep them in the same condition over a long period. So I was just wondering how everyone stores and preserves their vintage film? The ones that I have are 2 1/4" if that makes any sense. Thanks for any help!
