Hi everyone, I have recently decided to give home developing of C-41 a try but have a question about the kit I've purchased. I bought the 2 liter kit from Freestyle and am wondering if I need to mix the entire kit even though I may only do about two rolls at a time? If I do have to mix it all at once, what's the best way to store what I don't use? Can I just pour the used chemicals back in with what wasn't used or should everything live in their own container? From my search, bits and pieces of these questions were addressed, but not really in the fashion in which was helpful to me. Thanks!
