Response to HP5+ and Tri-X in Rodinal

In some of my experiments I found that HP5+ has a maximum contrast index (what we used to call gamma infinity) less than 0.65 in rodinal 1+50 and above. AGFA gives times for it in 1+100, but states the the maximum gradient will be 0.5, which they consider less than normal, and it would be less than normal if there is any flare in the camera. AGFA's normal is 0.65. Pat Gainer
