The very first time I used my ATL-2300 after I bought the processor and set it up I got a negative so bad that I could not believe it. I was in panic mode immediately looking for answers. Before that I had developed at least 100 rolls of 35mm and 120 negatives manually using a simple stainless steel tank in my bathroom sink. I never failed a process so badly. I was shocked. I paid thousands of dollars for the ATL processor and the result was much (I mean much indeed) worse than manual processing with simple tanks and reels cost no more than $50. Well, it did not take long for me to realize that the Jobo's guide for chemical volumes was meant to be something else. Kodak's tech pub has all the correct capacity data to be followed.
