One of the hats I wear is Archivist in addition to teaching physics and
photography. As such, I attended a one-day workshop given by James
M. Reilly, a recognized authority on the preservation ophotographs.
He suggested that a properly processed silver print could have a lifetime
of 100 to 300 years depending on the base and storage conditions. Illfochrome
classic color prints are claiming 300 years for laminated prints and are
willing to include a warrenty if you buy one.( Who will be around to
make the claim?) At the workshop, Mr. Reilly listed the factors that
could affect the life of a photograph. Exposure to UV light, of course,
and bright light in general, high temperatures and high humidity. At the
time (about 3 years ago) he suggested that high humidity was the worset

worst enemy of a photograph. Current research at the time was indicating
storage humidities of between 20 and 40% as desirable. He did say that
the ultimate would be a dry, cold, dark chamber would be best as a storage
facility. Frankly, I agree that works of art are meant to be seen. Museums
can be reasonable about it and try to maintain lower humidities and use
low level incandesent lighting. I would also like to point out that much
of what is done to preserve photographs, e.g. acid free matts and storage
boxes, UV filters on lights and in frames, dehumidifiers etc., is good but
it is also very expensive. Some archives cannot afford it or can afford
only part of it so the question becomes, "what do we preserve?" Conservation
is a relatively new field and was not taught as a general rule in library
schools until about two decades ago. Also we seem to be learning as we
go along. For example, I recently heard that modern RC papers may not
be so bad, archivally speaking, as everyone thought. Has anyone else
heard this?
