----- Original Message ----- From: "Lyman GL DeLiguori, Sr : Extremely strange indeed. Please see: : At first I thought it was just a typo, but I did find it in Section 14 : ("Diagnostic Charts" is the .PDF at the same URL above). See Chart E, 14.6. : You'll see it references adjusting the pH for the Green/Magenta shift. : : However, in a third search at yet another URL it speaks only of what we have : known: Yellow/Blue balance. : : Personally, after all these years working with E-6 I still think that's a : typographical error that has propagated. As you say, going Magenta/Green is : usually CD related (too much CZA from Part A, SpG issues, etc) and temp. : : Any other thoughts? Nope, no thoughts other than as you suggest, a typo repeated until it fell into being a stated fact (!) If I had ever seen a magenta/green reaction from a variation in pH, and I was always careful never to encounter a partA surplus. The only correction I ever made for this was to check and adjust the sg so I guess I'd keep doing what seems to work and ignore Kodak's suggestion! I have a set of the diagnostic charts from about 3 years ago somewhere here at home, but I really haven't refered to them in such a long time :-) k
