Looks like a cat’s tummy 2p nanosecs after it has bad cheeseburger. Cool.
How was the camera not destroyed in the blast?

Very cool. Thanks for posting this.
Fascinating, thanks for posting.
My Father worked with Edgerton, at NACA during WWll.
Scary images!
Interesting, I wonder if the actual primary detonation that sets off the Chain Reaction photos are classified. You could probably deduce the physical formation of the primary explosive to the critical mass.
How did they trigger the shutter at just the precise instant?
Have you found that in your reading?
The Kerr effect allows for very fast shutter speed but how is the time to trigger it controlled?
Several of them are eerie looking, like some sort of giant parasite giving birth. Others look like skull x-rays of an unknown species of hominid, hence the image of human skulls mixed in.

Bizarre.
Whoa! Bump!
In the early 70s I was interested in developing a camera to photograph guided artillery rounds leaving the muzzle and shedding protective devices around their guide vanes. The idea I worked with was a first generation image intensifier, which employed 45 KV DC between the photocathode stage and the third intensifier photoscreen. The EEs were able to switch this HV on and off very quickly, on the order of a few microseconds. By simply photographing the screen with an ordinary film camera (before digital cameras) I could get a usable photograph. We found that the pulse from the grid current caused undesirable distortion in the image intensifier. Didn't have time or funds to pursue that problem. Just some hardware we had on hand.
Years earlier I had worked with an EG&G microflash strobe and Speed Graphic camera to study the formation of molten ammonium nitrate fertilizer pellets being sprayed into a cooling tower. Learned that Lord Rayleigh had done pretty much the same experiments peeking through holes in a spinning disk, 80 or 90 years earlier.

Hey, those are some very interesting pictures. I’ve long been interested in nuclear phenomenology.
I do need to point out, though, that those are 10 nanosecond exposures, not images taken 10 nanoseconds after detonation. At 10 ns. after detonation, the fireballs could have been no larger than about 10 feet in diameter. Those are considerably larger. :-)
