Nuclear detonation from the "Tumbler Snapper" test series showing fireball and "rope tricks" by Lawrence Livermore National Laboratory  : The photograph was shot by a Rapatronic camera built by EG&G. Since each camera could record only one exposure on a sheet of film, banks of four to 10 cameras were set up to take sequences of photographs. The average exposure time was three millionths of a second. The cameras were last used at the Test Site in 1962. A paragraph from Michael Light's book 100 suns which includes this image and provides insight to the origin of such photos follows here: "At the still picture branch of the United States National Archives at College Park, Maryland, head archivist Kate Flaherty was unfailingly helpful during all aspects of research at that great institution, as were her staff members Theresa Roy and Sharon Culley. Roger Meade, chief archivist at the Los Alamos National Laboratory in New Mexico, went above the call of duty to make material available and help identify some of its more arcane aspects. At Lawrence Livermore National Laboratory in California, archivists Steve Wofford, Beverly Bull and Maxine Trost helped with image research. Nick Broderick, classification analyst at Lawrence Livermore, kindly provided final identification of notoriously difficult to attribute ultra-high-speed Rapatronic images made by E.G.&G. Thanks as well to filmmaker Peter Kuran for additional identification help with Rapatronic images."
