I develop 3 tanks simultaneously and have gotten good results (in terms of contrast and shadows) using semi-stand using Neopan @ 200 with Rodinal 1+50.
This way, I won't be too flustered trying to time every tank requiring inversions every minute as with standard development agitation schedules.
Does anyone have starting times for a normal contrast scene using semi-stand development using Neopan @200 using Xtol 1:1.
I define semi stand for me as:
Constant agitation for 30 seconds followed by 3 inversions over 10 seconds every 3 minutes.
Usually, I have up to 50 120mm rolls that I develop in a single session (10 tanks) so multiple simultaneous tanks are a must.
