Color Film Fade--- by Dr. Film

(Editor's note...... Color Fade and Vinegar Syndrome are the two headed monsters awaiting the unwary film collector. Thanks to Dr. Film for submitting his thoughts and this informative piece.)

Rx for Color Fade:

90% of the color film stock that you will encounter as a collector is "Eastman". You can determine the stock of a film by the printing along the sprocket hole edge of the film. Every few feet you will see the name of the stock and it helps to have a magnifying glass to read it. You can take your projector's lens out, turn it around and read the film edge easily with it. Unfortunately, all Eastman manufactured prior to 1982 has or will fade. Numerous attempts to restore this faded film have failed. Once the film has faded it cannot be reversed. Some projectionists use color filters in front of the lens in an attempt to restore the original color... it is a poor remedy.

LPP is a no fade stock made by Kodak since 1982 to 1992. It has a yellow-green bias in its color balance. Some collectors report that individual "airline" Eastman prints from the early 1970's, which used mylar (estar) as a base, are holding up well. However, many such airline prints are fading and should not be considered low fade.

Known as "New LPP" started to appear in 1992 and considered excellent low fade. Unfortunately not many prints came thereafter as video recording processes then began to dominate and film prints were no longer widely produced. 

Here are the color film stocks that have proven themselves to be low fade, they are: I.B. Technicolor; distinguishing itself as the real champ in holding its color. You can easily tell this stock by it's appearance... early stock had a blue sound track and usually soft focus and the more abundant later stock has sharp focus and a solid black sound track. Eastman LPP and the New Eastman(since 1996) are considered low fade. Very few "New LPP" prints were produced  since 1992 and they are holding their color as this article is being updated in 2018. Kodachrome and Anscochrome are holding up nicely. Bear in mind, any stock, even I.B. Tech, will change when subjected to high heat and humidity. In all instances one should be storing all stocks in a cool, dry place. Contrary to early hopes and observations, Kodak SP is fading.

The only way to fully arrest color fade in the fading stocks is the deep freeze. Second to that one should store their films in as low temperature and low humidity conditions as possible.
