    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???

    R9 developer is a DDR-erzeugniss, an East German B&W developer.
    ORWO NP 22 can be developed as Ilford FP4.
    I would try one rol first and see if you need some adjustment in your time, but it is a good starting point.
    I have been using NP 22 a lot, the NP 27 (Tri-X) even more and liked it.

    Peter is right NP22 can be considered similar to FP4. I think R9 is the same as RO9 in which case it is East German Rodinal a good developer time would be 9 mins 1:50 at 20°c should be ballpark.

    Thanks I will look up the times for FP4 in D76 and try that.
