Well they can oxidize. Mueums store in nitrogen. If you are as old or older then Jan then your cellulose nitrate can combust and needs a low Oxygen environment in a fireproof container. Black and white film is pretty stable when stored right. Movies are now archived be creating rgb separations. Technicolor in reverse. The process is interesting. What we do know is that a un used stored Hard drive can fail in as short as 5 years from demagnification so they had to find a better say to save color and new digital movies. THE SOLUTION
LASER scan color film
write out to 3 black and white seperations for RGB. Store in low oxygen environment.

The closest we have to laser scanners for still is the drum PMT scanner.
With all this talk about storage disasters and with unreadable data due to advanced hardware (and software?), I'm beginning to think that I have to print every image I want to save. Of course, that includes printing negatives as well so I'll still be able to print positives the old fashioned way.So, does anyone have good info on longevity of transparencies? Most of my images are black/white, so I'm mostly interested in black/white negatives.-yoramOn Jun 13, 2013, at 11:53 PM, David Dyer-Bennet wrote:
