I have never developed film before and I have read that it is best to start off with black and white developing because it is easier than color. I just bought a large lot of vintage film cameras (over 50 cameras) to clean and sell and there are a lot of half-used rolls of film in them that I will finish using and I want to learn how to develop them. In the lot, there were developing tanks, thermometers and the like. My question is they are all color C-41 film. Can I use my D-76 B&W Chemicals that I just got to cross-prosses and develop these? If yes, are there any specific instructions or issues that I need to be aware of that may be different from developing black and white film? Also, for people that have done this for years, any tips and tricks you would like to pass along? This would be my first roll of film ever self-developed and I am excited!! Thanks for your help!
