Finally getting to coming around to choosing from the many things I've tried. This roll is one of my favorites, 400TX, and done with stock D76. The difference in grain at 1:1 is too much for my eye. So stock it is. I did order up some HP5 to try though. Have to know for sure! Here is frame 37. Still having edge issues maybe. Need to concentrate on my agitation technique? Can't imagine what else it could be. Using fresh developer, same amount of fluid (250 ml) for the tank (Jobo 1510), Hewes reel, etc. Might be to quick during iversions or something.
