Because of the effort required to adjust the exposure the paper received, any irregularities in the film processing greatly complicated the adjustment of the paper’s exposure. The exposed paper was then developed in a similar wet chemical process. This chemical based paper requires precise exposure via an enlarger or automated photofinishing printer. Keep in mind, this film was designed to be processed to a color negative and then printed photographically on color photo paper. Over the years, the process has been shortened. Total wet time about 23 minutes 35 seconds. Wash in running water three minutes fifteen seconds.The C-41 process has evolved over the years becoming more environmentally friendly. ![]() The Kodak C-41 Color Negative Process, introduced in 1972 is an improvement over its predecessor, the Kodak C-22 Color Negative Process introduced in 1956. I would expect the Cinestill kit to be just as good. I doubt that the results are in any way inferior to full-scale, 'many-baths' C-41 development. I have used Tetenal's 3-bath C-41 kit quite a lot and also made traditional wet-prints on paper from the negatives. The working solution for most C-41 home use kits only keep a few weeks, while separate baths for large scale lab-development keep much longer and also have the ability to be replenished by replacing a small part of the working solution with fresh developer from time to time. It does however have impact on the durability of the chemicals. I doubt that this has any, or significant impact on the image quality or archival properties of the negatives. scratching.įor home use, the number of baths in the original C-41 process has been reduced by combining multiple steps into one bath. The hardening agent makes the emulsion less prone to mechanical damage like e.g. ![]() Since the emulsion is made of gelatine, it can be prone to fungal growth when stored, which is prevented by the first agent. A typical stabilizer bath consists of an antifungal and a hardening agent. Using or leaving out the stabilizer bath will not have any impact on the image quality, but may have impact on the archival properties of the resulting negatives. Since the stabilizer bath is fast and easy to use, I am not sure if I personally would risk leaving it out. They claim in their data sheet that modern C41 films contain embedded stabilizer chemicals, which are released during the first two baths, so that a separate final stabilizer bath is not necessary. The specific difference between the Cinestill 2-bath developer kit and the Tetenal 3-bath developer kit is that Cinestill leaves out the final stabilizer bath, or more precisely label it as 'optional'.
