A black and white photo of an atomic bomb test, taken by Edgerton with his Rapatronic camera. The fireball from the explosion has just erupted. It is roughly spherical and a several hundred meters in diameter. Small bright spots on the surface of the fireball are vaporizing chunks of the bomb's metal casing. Tiny silhouettes of Joshua Trees are visible in the foreground.

While working at EG&G, Edgerton and his colleagues developed the “Rapatronic” camera. Its shutter had no moving parts and could capture exposures as short as 2 microseconds.
This new camera allowed for high speed photos of atomic bomb tests. Notice the silhouettes of the Joshua trees in this photo.
