Tri-X 400 ISO developed normally in D-76 1:1 a total of 9 3/4 min at 68 degrees F. The Pentax 6×7 TTL light meter was used. Frame 3 used a RED filter +3 exposure. Bright sun except for frame 2 which was overcast. Sunny 16 matched in the forth frame shown and 6-8 were bracketed one stop each way. The last one was in heavy shade.
That is what Tri-X 400 looks like shot and developed as recommended.
