I have obtained a bunch of old ORWO NP-22 (ASA 125?) and NP-27 (ASA400?)
It have been kept well and I am going to have some fun with it.
I need some processing times with Rodinal, XTOL, D-76 something????
I was given a time of 11.5 min @69 in Rodinal 1:50 for the NP-22. I am going to try that in just a while but also need some info for the NP-27.
ORWO NP-22 is GARBAGE!!!! The best thing you can do is to send it to me for disposal, along with $20.00 for my taking the trouble to relieve you of your burden.
But seriously, I really liked this film in Edwal FG7 diluted 1+15 with plain water, developed for 7.5 minutes @ 70F, exposing at EI64.
Rodinal diluted 1:50 is another good choice for this film, using the times and temps for APX-100 as a starting point. I never tried the NP-27, so I can not comment on that film.
Be sure that you use a hardening fixer with this film.
