Ok. I'm confused. But aside from that for the moment, I just spent two hours trying to get fog on Tri-X. I took my dev (PQ Universal mixed at 1+5) from 6m to 16m in 2 minute steps. (I normally have been using it for 10m). Nothing. No fog. Is the PQ dev not energetic enough? What's happening? Remember that Ilford recommended it at 1+5 10m for their FP4 film. Do I need to go all the way to 20mins, double the concentration, or go for Dektol?
