that the color of Agfa slides maintain the best color over the years. These images I'm scanning were taken by my mother in the late 60's to early 70's. Using my Coolscan, the color of the Agfa slides remain rich and clean. A lot like the current fuji slides of today. Just an observation.

What were the other slides? Can't speak for Fuji film, but looking at my slides (which date back as far as 1982), it always seemed to me that Kodachrome held up the best over time, with Agfa second, and off-brand ones at the bottom. In the 1980s, I used a lot of Revue slide film (not sure who actually made that) while living in Germany, and 20 years later most of those slides are $#!# with color shifting etc.
