Found some old slides I'd taken as a boy in 1967, surprised to see that they're Kodachrome, still looking great, but some of them have occasional places where the emulsion has flecked away. (Parenthetically, they were taken with a Kodak Instamatic -- Kodachrome 126! Whoa.) Anyway, I've decided it's time to shoot the big K while it's still possible. My question is about storage. How do other Kodachrome users store their slides? I want to avoid emulsion damage such as I found in the 40-year-old negs. Thanks!
