Addressing 2020 complaints in the "box"
[edit]Addressing the "issues" in the box, indeed it is written like a guidebook, and also, quite indeed, it is like a "technical manual," as Ektachrome processing is tricky if someone is referencing this article. As for the "single-source" complaint of the veracity of this article, I referenced Kodak Process manual Z-119 — Kodak invented Ektachrome; and Fuji adopted it in their 100%–compatible Fujichrome film and developer chemistry product lines. When in doubt, "go straight to the horse's mouth."
Source of Formulas
[edit]The recipes and formulas probably belong elsewhere (not in Wikipedia?) -- Egil 20:35, 17 December 2005 (UTC)
Yes. But can someone claim copyright on that ? Ericd 21:24, 14 March 2006 (UTC)
Not sure if copyright can be claimed, as the formulas are available publicly. The original source should still be cited though. htmlguru4242
I think its some ISO standard now ? Ericd 19:05, 17 May 2006 (UTC)
Temperature Units
[edit]The temperatures aren't in proper Celsius SI units, and this makes it very difficult to interpret as my grandparents died about thirty years ago. Ian Tindale 09:12, 29 May 2007 (UTC)
- The process specification is actually in F degrees asit was speced out in the USA. Feel free to add the SI equivelents in brackets cmacd 12:49, 29 May 2007 (UTC)
Moving 3 bath hack to the discussion page?
[edit]Any comments on moving the three bath Tetenal hack to this page? Discpad 00:23, 26 August 2007 (UTC)
Still a work in progress
[edit]Hang in there: I still need to edit some more, especially the fixer formula, since ammonium thiosulfate is needed for the more vigorous fixing action. Discpad 02:03, 26 August 2007 (UTC)
Solutions for the Watkins chrome brew formula
[edit]I moved the formulas here, because although they will (barely) work, they produce erratic results. Discpad 01:18, 26 August 2007 (UTC)
Warning: The ferricyanide bleach in the Watkins recipe .[1] will cause excessive dmin in the film without a clearing bath and may hurt the image. Ektachrome films were designed to go through a Ferric EDTA bleach instead.
Caution: The phenidone-hydroquinone developing agents are Not Recommended, because they cause color crossover, bad grain, poor sharpness, and so on.
Note: A Sodium Thiosulfate fix will not be strong enough for E6 films without using very long fix times - Stick to commercial ammonium thiosulfate fixer, which is both inexpensive and plentiful.

Restoring citations
[edit]The citations are correct, as they come directly from the Kodak Process E-6 manual and more extensive Q-Lab manual. Someone vandalized the page by removing the citations, then someone else came along and wrote "Gee, there's no citation!" FML
Why there is no negative dye image?
[edit]Can someone please explain, why in the first step there will be happen no colour coupler to colour dye transformation? As far as I understood, during developing a silver image, the colour couplers will be changed to actual colours. This must be omitted here to prevent developing a negative dye image, doesn't it? -- Pemu (talk) 17:30, 28 July 2015 (UTC)
