Four to 10 cameras
- “The exposures were often as short as 10 billionths of a second, and each camera could take only one photograph. As a result, banks of four to 10 cameras were set up to take sequences of photographs during a single nuclear test.”

Aug 1, 2023 · In 1955, in what is called Operation Teapot, 48 cameras were set up at distances that ranged between 838 to 3,200 meters (2,750 to 10,500 feet) away from ground zero – the site of the explosion...
Jul 4, 2023 · For this test, government officials arranged 48 cameras 2,750 feet to 10,500 feet from ground zero, according to a 1955 report on the technical photography of the nuclear test from the Defense ...
Jul 31, 2023 · “The camera setups were designed to stay in place and handle the blast pressure,” Peter Kuran, owner of AtomCentral and a film producer of multiple atomic bomb testing documentaries, tells...
Jul 10, 2017 · According to Appendix I of Mack’s “July 16 th Nuclear Explosion, Space-Time Relationships” report on the Trinity Test, there were fifty-two different cameras used to capture the test on film. Of the fifty-two cameras, there were the following number of each type of camera: 3 Fastax 8 mm cameras ; 3 Fastax 16 mm cameras; 3 Slow Fastax 16 ...

In this film, a device airdropped from about 12,000 feet above the Pacific detonates on October 30, 1962. The film shows the two characteristic light output pulses that are seen only in nuclear weapon blasts, which correlate with the device’s yield (the amount of energy given off from the explosion). The first pulse occurs when the shock wave forms...
Tesla was a relatively low-yield shot of seven kilotons, dropped from a 300-foot tower at the government’s test site in Nevada on March 1, 1955. When the shock wave hits the ground in the video, it kicks up the dry desert soil and “it makes a nice little dust cloud,” Spriggs says. After the second pulse of light reaches its maximum, the bright whit...
The Nutmeg test was detonated from a barge tethered to Bikini Atoll in the Pacific on May 21, 1958. In this film the initial blast and scattering of light are visible but high humidity obscures the fireball itself. As the shock wave travels away from the blast, it changes the atmospheric pressure and creates a low-pressure trough in its wake. Conde...
The Bighorn device was dropped over the Pacific Ocean from a height of around 12,000 feet on June 27, 1962. Thanks to the high altitude, the detonation occurs above the humid layer of the lower atmosphere. The bright light erupts from the second pulse, and then the gases start to escape. As the shock wave propagates downward, it flows through the m...
Jul 17, 2023 · The report stated 48 cameras were placed in distances ranging from just under a kilometrefrom the bomb detonation site of ground zero to3.2 km away. There were interior cameras in six structures of varying heights and composition, from basic wood frame to masonry, concrete and cinder block.
Aug 4, 2023 · Many cameras were set up at fixed locations, some as close as 800 yards from the explosion. To ensure that these cameras could work through the blast, they were set up in shelters, angled facing ...
