Summary

DescriptionTumbler Snapper rope tricks.jpg	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.

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/
