It needs to be mentioned that not all 20-year-old film is equal (we all know 
the principles, but we don't often encounter the examples head-to-head). :-)

If film is stored in a cool, dark, humidity-controled environment, its 
lifetime is very good over a period of 100-years or so--providing that the 
film base and chemicals were "archiveable" in the first place (and not all 
were). Some of my mother's slides are 52 years old--only a few of them are 
degraded: some by obvious light exposure, some by dust, a very few just 
faded (poor dyes or development).

But both Hersch and Maris are right. Film is stable, and so are digital 
numbers; the problem being that *nothing* is really permanent, so continuous 
and redundant archiving, at this point in time, is the safest way to 
approach this problem.

Best regards--LRA
