Extremely strange indeed. Please see: http://www.kodak.com/global/en/service/Zmanuals/z119.shtml Select the third .PDF file (Monitoring and Controlling Processing Solutions) and go down to Section 3.3. On the lower right you'll see where it speaks of correcting the Magenta/Green curves. 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? Many thanks!

Okay...maybe if I were a bit more specific. I need to : inquire at the Pro Processing Level as to why Kodak is now using 5N-NaOH and : 5N-H2So4 for pH correction of the Magenta/Green layer. For years on end pH : corrections were only made to the Yellow/Blue layer. that's odd! magentra green issues are usually CD concentration and temperature related, as you say, blue yellow is controlled by pH. How recent is this guide or suggestion about altering pH - is it something published on the Kodak site ? k
