The first light of the Trinity test, the first atomic bomb detonation, burns through film emulsion. New Mexico, July 16th, 1945, 5:30am
The photo was by Brlyn Brixner. He was a real innovator in photography and an official photographer for the Manhattan Project. Brixner had something like 50 cameras set up that day, of all different types. Some could record at speeds of 10,000 frames per second.
If you watch the film footage that Brixner shot, you can see that the ball goes out of the frame briefly before the camera shoots up to follow it. This was Brixner’s fault. As he later said in an interview:
I was so amazed, though, initially that I just let the camera sit there. Then suddenly I realized that the ball of fire was going out of the field of view… for the first twenty seconds on the standard-speed camera it’s just sitting stationary, then suddenly you will see the field of view jump as the ball of fire is going out of the top of the frame.
