Automatic Camera situated 7 miles from blast with 10 foot lens. Shutter speed equaled 1/100,000,000 of-a-second exposure. Joshua tree's near base get vaporized in just microseconds.
I believe that the 1/100,000,000 is fairly accurate. I will be looking in to this to see how it was done. You have to remember it was an atomic bomb. This is a series of three photographs.
Good catch, Zowie - I must admit, I quoted the website directly on that and had no idea on what the shutter speed equivalent of taking a blast 7 miles away with a 10 foot lens.
