Heated beakers with plain water, CD, blix, and stabilizer in a dishpan with hot tap water to 88F. Poured in the water and inverted 15 times slowly to warm up the tank and film. Then proceeded with the CD and blix -- each with 5 initial inversions and 3 inversions every 30 seconds. For the rinse, I used warm tap water for fill/invert/discard 5 times, then fill/invert n times/discard, where n = 2, 5, 10, 20, 20. This took about 5 minutes. Then stabilizer for 15 inversions. Then 1 wipe with a squeegee and dry.



I was pleasantly surprised with the results; sample attached. I was even more surprised when I found out that I had screwed up the development time. I didn't have my reading glasses with me when I did the work, and misread the development time. So I only developed for 6 minutes. I noticed it should have been 8 minutes later when I read the instruction sheet with my reading glasses on.



My sincere thanks to Martin and the others who have contributed to this thread. Hope this helps anyone interested in C41 processing.

Attachment 78739 Attachment 78740 Based mainly upon this thread, I got a Tetenal kit and just used it for the first time. My aim was to establish a procedure similar to my traditional B&W processing. I noted in the instructions that Tetenal provided an alternate processing method for 86 degrees Fahrenheit, so decided to try that on the first roll. The method calls for 8 minutes CD and 6 minutes blix. I like the longer times (less susceptible to minor timing errors) as well as the lower temperature (easier to get to and maintain). I'll post a scan of the instructions. I use stainless steel reels, so the method was as follows:Heated beakers with plain water, CD, blix, and stabilizer in a dishpan with hot tap water to 88F.
