Summary

DescriptionTumbler Snapper rope tricks.jpg	English: 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. Deutsch: Operation Tumbler-Snapper: Der wachsende Feuerball einer der Snapper-Explosionen. Das Bild wurde mit einer Rapatronic-Hochgeschwindigkeitskamera etwa eine Millisekunde nach der Detonation aufgenommen. Der Durchmesser des Feuerballs beträgt etwa 20 Meter. Die scheinbaren Ausstülpungen an seiner Unterseite sind durch Befestigungskabel des Bombenturms verursacht, die die Wärmestrahlung des Feuerballs absorbieren. Diese Ausstülpungen werden als „Rope Trick“-Effekt bezeichnet.

current	13:19, 17 June 2011	922 × 852 (90 KB)	Jakuzem	Removed black margins (not noticed before), so there is only better contrast and lack of moire but not increased resolution compared to the original version.
	12:49, 17 June 2011	1,247 × 852 (108 KB)	Jakuzem	Found higher resolution version of the picture, with better contrast and without the moire due to scanning a printed image. Found at: http://www.howtobearetronaut.com/2011/05/nuclear-bomb-tests/
