Hi guys,
First time poster here. This forum is a fantastic resource, so thank you to all who contribute.
I've done a lot of searching, but haven't found the exact answer I'm after -
I'm using Bergger PMK Pryo for the first time to tray develop FP4+ 4x5, shot at EI125.
I'm unsure what my N, N-1 and N-2 times should be.
The Bergger instructions lists N as 12min at 21C/70F, but that's for EI160.
Massive Dev Chart says 10min at 20C for EI125.
As I understand it, it should be around 10-15% change for N-1, so as a starting point would this sound reasonable? -
(20C)
N: 10:00
N-1: 9:00
N-2: 8:00
Any help is appreciated.
