Conserving Color Negative and Slides

[xlaburu]

Hi, I hope someone can help me out with this.

I have several thousands of negatives/slide films archived, from these 20% or a bit less are B/W and I know the different chemical processes to prevent the silver degradation of B/W film, like Selenium, Kodak Gold Protector-2 (don't know if it is discontinued nor it's price though) and the Polisuflide one. This is fine, I still have to experiment with all of these excep the Selenium one, that perhaps is the less recomended for Film.

The case is:

Is there any such conservation chemical process worthie for colour negative and slides? Or the only way to keep these preserved with no major tone/color changes is to have them in a good tempreture, low humidity, little light, and decent air conditions?

Thank you very much!

Just scan them and store them properly.

Scanning is not archiving. There is no digital archive. If you're really interested in "archiving" the color negs, store them at 50˚ at 50% humidity. Freezing also works well according to (now bankrupt) Kodak.
