Finaly developed one more film. Exposure index = 50. This time did Fomadon R09 1:50, 20C (68F), 8 minutes, agitation for first 30 secodns and then 2-3 "turnarounds" avery minute (basically followed Field's experiments / recommendations). I love result. I do not see that much difference from a "normal" bw film (except black roses).
Now I'm torturing myself why I did not buy more rolls from Field when they were cheaper..
