![]() ![]() I found it gives parallel characteristic curves, but it must be used at 100F and pH adjusted to 10.0 to 10.2 to achieve these results, similar to commercial developers. Sanking, if you decide to mix your own, here is a simple developer formula to try: I'm not suggesting you copy Bertram's method, but his article is very interesting. I tried his technique and after running Kodak C41 control strips and having them read at my work, the results were so good, a visiting Kodak chemist who had got wind of what I was achieving in a home darkroom, one day asked how I was doing this. To that end, he started using Part A of Kodak's C41 developer with bulk chemicals, ending up with excellent results. this article did give some insight into C41 chemistry and no matter how much he tried, he just couldn't emulate Kodak C41 chemistry. ![]() This appeared in the Nov/Dec 1988 edition of Darkroom & Creative Camera Techniques, pages 23 to 25. Miller had an interesting article called "Managing Your Color Photochemistry" subtitled, "Keep a Balance In Your Darkroom." However if one developed a Kodak control strip and had it read at my work (Industrial colour lab) the parameters weren't quite there.įast forward to November/December 1988 and Bertram W. This was in the mid to late eighties and within reason, one got very good to excellent colour negatives for wet printing. The other two were ones that I had picked up here and there. I did C41 using about three different C41 formulae, one was from a local industrial doctoral chemist, which worked the best.
