- | I looked this up in Pop. Photo's June 1990 article on color material
- | stability. This was an article on longevity by an expert, with lots
- | of hard data and tables on just about everything. Most excellent.
- |
- | A few results (from memory):
- |
- | Light Dark
- |
- | Kodachrome 1 hour 500+ days
- | Fujichrome 5 hours 200+ days
-
- I've seen quite different numbers in various European photo magazines, both
- professional and amateur ones. The Fujichrome 50 and 100 slides lasted longer
- than five hours during projection and Velvia almost as much, but not quite. For
- storage in the dark, both survived significantly more than 500 days. Fujichrome
- was in the 50 year range, Kodachrome in the 75 year range and Ektachrome and
- Agfachrome in the 25 to 35 year range.
