I have some questions about the capacity of C-41 Kodak Flexicolor chemicals. This is the first time I buy these chemicals and process C-41, so I want to be sure about it. I use a 600 ml Paterson tank which can process two rolls.
Feel free to answer any of the questions.
CAPACITY
1) The developer is easy. I use it and discard it, so I have no doubts about it. When I expose two rolls, I prepare 600 ml of developer using syringes.
2) Bleach, Fixer, Final Rinse: How many times can they be used? A Kodak paper says that a quart/liter of any of them can be used for ten 35mm rolls. Is it like this or do you use them more times? Do I have to add time to Bleach and Fixer processes every time I develop or it is not necessary?
3) I have a 1 liter bottle of Bleach (used pure). But I have mixed a 720 ml of Fixer, one half water, one half Fixer, so how many rolls could this bottle fix? I suppose it is proportional, if a liter can process 10 rolls, 720ml can process 7 rolls...
4) Is there for Flexicolor Fixer a test like the one used in B&W fixer, calculating the double of the clearing time? What calculation must be done?
5) Kodak says in its Flexicolor paper that solutions of Bleach, Fixer and FR must be used ideally for no longer than 8 weeks once prepared. I use the Bleach pure, so I don’t think it could be considered a solution. But my bottle of Fixer would be a mixed solution, because it is half water, half fixer. So should I discard the fixer by now? I prepared it like 7 months ago (and by the way, yesterday I used it, without knowing this, and it seemed to work fine). Also, if the 1:1 Fixer is only good for 8 weeks, this would be different from the B&W fixer I use, which lasts much longer.
6) So far, I have been using the Final Rinse one-shot, just like I do with Photoflo in B&W. But apparently it could be used more times. Should I prepare one liter and use it for 10 rolls?
USE AFTER EXPIRATION DATE
7) How longer can each of the four chemicals be used after the expiration date indicated in the bottle?
In my case, the Bleach I am using has already expired. The Fixer expires this month, 11/17, and I still have a lot and I don’t shoot too frequently. The Developer and FR expire by mid-2018.
