Hi Everyone,
I just purchased a CPE-2 processor and have been reading the Jobo manual about B&W film development. I don't understand the reference to the min amount of active developer. A 1520 tank has a capacity of two rolls of 120 or 35mm film.
I have been using D76 mixed 1:1 when using the inversion method do this was not an issue. The manual states you need 240 ml to develope two rolls, but they also state in their literature that a min of 110 ml of active developer is require per roll of 36 exp. 35mm. They recommend incresing the amount of developer by 30%.
Do most people use D76 straight or are they using more than 312+ ml to develope two rolls? For example would you use the 240 ml for a single roll of 120 or 35mm with D76 1:1? or say 330 ml mix 1:1 for two rolls?
Does this become more pronounced with the more rolls you want to develope?
If you add a 1530 extention you can develope up to 6 rolls of 120 or 5 rolls of 35mm. Data sheets recommend 570 ml, but do you need 110ml/roll or 660 ml for six rolls of 120 film? The manual recommends not to exceed 600 ml.
Thanks in advance,
Jason
