Hallo, ich habe gerade eine größere Menge alter Orwo NP 20 Rollfilme erworben. Allerdings konnte ich auf dem Beipackzettel keine Entwicklungszeiten finden....

Hello, I’ve just bought a large batch of old Orwo NP 20 roll films. However, I couldn’t find any development times on the instruction leaflet. Would it be possible for any of you to tell me the development times and agitation speed for R 09 1:40 at 20°C? Best regards, Wolfgang

Gast

Wolfgang, I don’t have the times for R09 to hand, but a few years ago I scanned the original instructions for A49… and lo and behold, I’ve put them on our website too: http://www.fotoimpex.de/Technik/technik.html and then “Instructions for A49 Wunderentwickler”. So at least the times for the good old (and now probably rather soft and grey) NP20 for the A49 are listed there. Best regards, Mirko

Hello, here are the times from Junge/Hübner: Photographic Chemistry, p. 143, R09 1 + 40 9 to 11 minutes with constant gentle agitation. Size Manfred

I’ve got a list of some of the most common developers for NP15, NP20 and NP27. I can email it to you as an Excel file or perhaps as a PDF (if I can convert it). Uwe

Thank you so much for your prompt help!!! I developed the film for 11 minutes in R09 and am very happy with the result!! Best wishes to Otto, Manfred, Uwe and Mirko :rolleyes: Wolfgang
