Atomic Bomb Detonation
This website has a handful of pictures showing the initial moments of an atomic bomb detonation. The explosion looks nothing like one would expect; it looks vaguely organic.
Automatic Camera situated 7 miles from blast with 10 foot lens. Shutter speed equaled 1/100,000,000 of-a-second exposure.
I always have a vague fascination with pictures of Nuclear explosions. They're very beautiful, and yet they scare the hell out of me.
