Hi guys, I've been doing my own B&W developing but never done color negative films. I just purchased the Jobo CPE-2 and Unicolor C-41 2 liter kit from freestylephoto to develop some color negative films and I'm confused. I'm planning to mix only the half ( 1 liter) so I could use my 1 liter accordion bottles and save some $. So,,, let's say I have my chemicals in 3 bottles (1 liter) and I want to process 4 sheets of 4x5 films in the 2521 tank then,,, 1. I only need to get 300ml ready for each developer, blix and stablizer. Am I correct? 2. Can I re-use them for 20 more times even though it says use it for 8 times on the box? I think I read it on other forum or somewhere. 3. Do I keep the other 700ml in the fridge? 4. After re-using the 300ml 20 times, then I get another 300ml from the 700ml bottle ( in the fridge) and use them for another 20 times? Please correct me if I'm wrong. Thanks!
