I recently tried tri-x after using hp5 and tmax. I developed stock in D-76 for 6m 30s just as kodak states it to be for the temperature of the dev. However I felt that my negatives didnt come out with as much contrast as I was expecting. As I state before I use D-76 developer. Anyone have any other "recipes", as in times of both Development (and at what temp) and time for Fixing for tri x? Im looking for a good amount of contrast any suggestions?
