Almost all of my Kodak colour negatives from the mid 1980s and earlier
[mainly 100 ISO] have suffered a severe loss of green pigment [or have
accumulated an excessive amount of red!]. The strips have been stored in
plastic sleeves, unfortunately not of archival quality, in a ring binder
away from the light, in a basement room with a temperature with a fairly
constant temperature about 65 / 70 F.
When scanned the negatives are excessively red. This excess can be
negated by adding green but the on screen images then appear to more
grainy than should be the case.
Is the loss of green pigment in the negatives a function of time and to
be expected, or from not being stored in archival quality sleeves, or
from being stored at too high a temperature?
What is the best advice for storing colour negatives so as to minimize
the chance of deterioration or at least to prolong their colour lives as
long as possible?
All and any helpful comments will be appreciated.
Thanks
John Hudson
