Well since the film I have from HS is some 30yrs
old, and has been treated awfully for the most part, and still hasn't shown
film-base deterioration, I don't think its nearly as big an emergency as the
below describes.

Thanks very much, Tony. That was quite an
education. I guess that has to be factored into the discussions of the merits
of CD-R archives vs relying on the permanence of the original negatives and
slides.

Oh, you might think so ;) - but see below
Nishimura is
based at the Rochester Inst. of Technology Image Permananence
Institute,
so appears to know his stuff.
It will give anyone who has been taking
photos over the past 30yrs the

Warning: Negative
base deterioration
If you haven't been using polyester based film
(such as Kodak Estar
base films), then I expect that most of you won't
have any negatives
left within a few decades. Let me give you the sad
story first before
I talk about the whys and hows. I got a call around
1992 or so from
Evelyn New York photographer known for her coffee
table books in the
1950s and 60s of European cities. She called because
she went into
her negative collection and found that they were all badly
distorted
and the emulsions were lifting off. We had been researching
this
problem since 1988 and were very aware of what the problem was. I
had
to tell her that her life's work (other than what books and prints
were already out in the world) was gone and there was nothing that
could be done. A few could be saved by special methods, but it's so
labor intensive that of her thousands of negatives, it would only be
worth treating a couple.
