[Fred W. Schneider III]

I've seen some of the 1936 Kodachome (movies that Bill Moedinger took)
that had turned totally magenta (like the Ektachromes I took in 1960).  

The Kodak tech rep I was listening too on Monday described color films
as green and red ... claimed they start off green and age to red.  The
amateur films allow a considerable range (within the acceptance of the
public).  The color "professional" films are allowed by Kodak to age
until they are neutral, and are then refrigerated.  Maybe the yellow and
blue Ed mentions was a similar phenomenon associated with the early
Kodachrome ASA 8 materials (or was that ASA 10, Weston 8?). 

In addition, no two batches of film are absolutely identical ... they
range in all directions from neutral ... red, yellow, orange, green,
blue, violet ... within tolerances that Kodak feels the public accepts. 
Historically, the tolerances for negative films were greater than for
transparency films.  I could give the numbers but their meaning would
sail over the heads of most of you.  The professional films (or at least
some of them) may have the correction filtration printed on the
instruction sheets ... such as +2 cc blue or -1 cc magenta ... telling
you what must be done to neutralize the color.  I know that Ektachrome
Professional in 1960 had the corrections on the instruction sheet (I
used a roll in Paris).  And the color slide duplication films today are
shipped with corrected values.  I can't testify about all pro films from
Kodak.

Applies whether shot in Europe, Johnstown or Pittsburgh.....
