Sorry for some of the confusion. This is 35 mm HP5 and Tri-X - the ISO 400 variety. I was using the Massive Development time rather than the Ilford time because I was going by previous experience. I have shot several thousand rolls of Tri-X, Neopan 400, and HP5 over the years - the publisher bought the lowest price so we switched back and forth, when photojournalism was analog. I never had this problem with either grain or contrast, so I'm not making the statement from 'just one roll.' Again, sorry for the confusion. Thanks.
