Some boxes of old slides were passed to me recently by a relative. They were
in dirty yellow boxes "stored in the garage". All were Kodachromes and
Ektachromes taken by my father from 1958 through 1972. The Kodachromes are
stunning! The 1958-64 version of that film is awesome.

The Ektachrome slides are less true to the originals, faded, and in a few
instances severly discolored toward yellow. Some Ektachromes are good enough
to project and many can be cleaned up in Photoshop. Those in Kodak
processing mounts are in much better condition than slides in independent
lab mounts.

My experience with old 'chromes largely matches Bill's with a few
exceptions: the images are my own, dating back to 1952; the majority of
slides processed by unknown labs, i.e., not mounted in Kodak frames, have
fungus spots; and all the Kodachromes I shot in India in 1988 have a green
tint. I'm guessing that the green shift was caused by carrying the films in
my backpack for several weeks in climatic conditions that included very high
heat and humidity (monsoon season). The chromes I shot in North-West
Pakistan on the same trip were not so affected. Trying to correct the green
shift in PS6 will be an annual winter project...
BTW my wife recently found some of my negatives (her method of storing
photographs is more casual than mine) which turned out to be from the early
days of chromogenic b&w. The Ilford XPs are in decent shape for scanning.
The corresponding Agfa films have decayed rather badly.
