    Another issue, some plastics degrade over time, so an older plastic paper safe, may still be safe enough for B&W paper, but not for colour paper or film.

    Well, all, I certainly got rid of some faulty presumptions. Thanks all.

    Yes, color film is very sensitive and about 5 inches, laid carefully on the back of your 35mm SLR, is probably the BEST way to tell if your camera has light leaks. - David Lyga
