When I saw what John Sexton and Clyde Butcher were able to do with TMAX I wanted to be able to do the same. That was quite a while back. Needless to say, I was really disappointed at first. For the longest time, and I am talking about years, I couldn't get results that I liked, even though TriX, FP4, PanF, and HP5 were working for me. Finally, in 2007, I found a combination of exposure below 100 and development in PMK that produced something I really want to be able to recreate and keep using, and hopefully even improve on. For me, it has been a long and I would also say somewhat expensive road, but worth it, and I would guess that there is still more that can be obtained with this film, if I keep improving my methods. My luck would be that now that I havve decided this is a favorite, they will discontinue it.
