I am new to B&W and this is the first time that I have tried to determine my own film speed and developing time. Here are my results: 20min at 20 C, 1:2:100 (parts A:B:water)(posted 9714 days ago)EI 50
Zone I Zone V Zone VIII OD 0.12 0.85 1.24 0.10 0.88 1.26
EI 100 Zone I Zone V Zone VIII OD 0.03 0.62 1.19
It would appear that EI or 50 is correct based on zone I readings.With the developing time of 20 min, zone VIII also looks pretty good, but zone V is too high. If I reduce developing time down to 15 min then zones I and V are OK (approx 0.1 and 0.65) but zone VIII is too low (approx. 1.1). Any suggestions on what I should change in order to get things right? By the ways, I am using a condenser enlarger.
thanks, mike
