So the old abage "better is the enemy of good enough" holds once again. I've changed my old trusted Rodinal in which I used to develop HP5+ for D-76. Being a bit worried about excessive contrast, I diluted it one to one and develop the film - which, as far as I recall, exposed at 320, if it matters - for 11 minutes. The time was taken from the film box. I haven't made the prints yet but it looks to my unexperienced eye as the negative was lacking contrast, a bit underdeveloped. Is it the characterstics of diluted D-76 or the time was too short? DigitalTruth says I should have bathed the negative for 13 minutes. Once I've listened to what vendor says and it happened to be not the best idea. What are your experiences with 1+1 D-76 and HP5+?
