The manual I have,TM 1-219, was written under the direction of the Chief of the Air Corps. There was no separate Air Force at the time, so the front cover only mentions the War Department. It is truly basic photography. I suspect that most of the formulas were designed to be capable of high contrast for aerial photography.
