I've done a search through the forums through 15 pages and did not locate an answer. As I am new to the at-home C41 development process, I would like to learn some best practices and then some actual practices when it comes to using this kit. Firstly, the supplied instructions state that 8 120 rolls can be safely developed in the chemicals. However, a search on flickr seems to have a consensus of 3 times this amount (24 rolls) can be developed with this kit prior to exhaustion. Secondly, what does exhaustion look like? What effects become apparent on the developed negatives? Thirdly, can I transition this exhausted chemistry to cross-processing duty, as color integrity (which I assume is the first effect upon exhaustion) is not important? I would appreciate any additional words of wisdom that I may have failed to ask or be aware of. Thanks!!
