    I'm a grad student and my area of research is digital restoratioin of
    colour slides and photographs. I'm trying to find information on dye
    fading stability of Kodak Ektachrome colour transparency films,
    particularly processes E-3 and E-4.

    Ideally I'd like to find some data how C, M, and Y dye densities
    change with time, as well as time-based changes in side absorption.

    I'm not sure if Kodak has ever published anyting on the topic - all I
    found was a publication on process E-6 stability (Kodak Publication
    E-106), which I'm trying to track down. I'm curious if anyone knows of
    any other published data - I'm sure someone at some point has
    conducted light- and dark-fading tests on Kodak films and I'd really
    like to find this data.

  2. The following sites may have useful information:

    The Image Permanence Institute of The Rochester Institute of

    The American Institute for the Conservation of Historic and
    Artistic Works at: http://aic.stanford.edu/

    Conservation On Line site at:

    Also, if you are in the USA call Kodak's customer service
    number 1 800 242 2424 and ask for extension 19, the
    professional group. They might be able to guide you to Kodak
    sources and possibly other sources. There are many other
    sources but these should get you started.

    There is a very large body of literature on the
    permanence of photographic color materials. The motion
    picture industry especially has been very interested in this
    for years. You are probably going to have to do some
    old-fashioned research at a good university library in
    addition to the web stuff. A good source for motion picture
    oriented articles is:

    Google Henry Wilhelm he's done a lot of research on dye
    stability not sure how much pertains to E-3 and E-4 but his
    book on color print stability was a landmark when published.

    This is totally unscientific, but yesterday I was looking through some
    of my father's slides from 1959-1961, vacations and parties and such.
    Most of the Ektachromes have turned into something almost like
    monochrome, varying intensities of reddish-brown. A few rolls of
    Ektachrome have held up better and one can still guess at the original
    colors... not sure why those particular rolls held up better than the
    rest. All the Kodachromes still look great, bright natural colors. All
    of these were shot on commercially available 35mm amateur film (on a
    Kodak Retina Reflex if anyone cares), processed by Kodak (probably at
    Fair Lawn, NJ), and have been stored in identical plastic pages away
    from light at "typical" household temperature and humidity. I don't
    know which Ektachrome process was in use at that time.

    [snip empirical data]

    Unscientific, maybe, but extremely useful information, I'd say.

    Any system of knowledge that is capable of listing films in order
    of use of the word "****" is incapable of writing a good summary
    and analysis of the Philippine-American War. And vice-versa.
    This is an inviolable rule.
