Developing Orwo Wolfen NP100 B&W film

[AveryWagg]

I just bought a couple of rolls of Wolfen NP100 (100 ISO), and the data sheet that comes with it suggests using ORWO 17, or Kodak D-96. Well, alI I have at home here in either TMax dev, or D-76. I had never ever heard of those developers before. The Massive Dev chart doesn't have NP100 listed. Does anyone have any experience with processing this film?

Good question. Since the film is probably expired I‘d shoot a couple of frames at different ISO settings and develop in D76 for an average amount of time (6 - 8 minutes?).

Is it somehow similar to Apx 100? Orwo and Agfa have the same origin before hot/cold wars.

D96 is not terribly different from D76, but tends to be a little slower. The NP100 data sheet says 5-8 minutes in D-96. So you could try 5-6 min in D-76.

A ring-around will help you determine exposure and a development time without a densitometer or other equipment: Johnston's Not Much of a System System

Thanks gentleman! Those are the tips I needed..
