I have a couple of rolls of ORWO NP22/120 that was given to me by another APUG memeber. I have shot the first roll and need to know about processing the film. I usually use D76. The instruction that were in the box call for "R9" developer??? I found one refference on line to d76 for 10-12 min. It did not reference the dilution. Stock, 1+1, 1+3???
