Quality of slides

[marklewis]

I do quite a bit of scanning of slides. I've noticed of course that some are lighter or darker than others due to exposure. However I think some makes of slides age better than others. Does anyone have information about makes or types of slides that last better than others? Thanks

Quality of processing and then the storage of the slides have more to do with it than brand of film.
Air, heat and sunlight are the enemy of slides. Store them in a cool dry place preferably in a metal or acid free plastic slide storage box.
I receive tons of slides every month for scanning or printing. Even very old Ansco slides hold up well when well stored.
Of all the films though, Kodachrome seems the most archival, but see above.

I hate to just offer links to other sources, but I think that is appropriate here, as very few people are experts on this subject. A quick and interesting narrative on the topic here, or more than you'll ever want to know here (http://www.wilhelm-research.com/). Henry Wilhelm is the world's indisputable authority on the archival characteristics of film. Bottom line - cool and dry storage, and if you're going to scan your slides then do it right the first time!
