I do not know if we should. I do know I went out the morning I took the shot with my Nikon F4 and Voigtlander 40mm F2 Lens. I was shooting Kodak Tri-X 400 and pushing it 2 stops to 1600. I wanted a high contrast shot and when I saw the two gentlemen I knew I had it. I then developed it in Tmax developer 1:4 for 8 minutes 45 seconds at 20C (68 degrees F).
