He has used both Tri-x & Delta 100 with the former not enlarging as well as the latter. He uses camera to capture his vision but doesn't compose that vision on ground glass, ie crops. It works for smaller prints but the loss of information thru cropping does impact his larger prints. Does use a wide angle to get better dof. In sum, he has great vision but camera/darkroom techniques probably adversely impacts the final print ( see Masters thread for long discussion of this issue).
