damninteresting.com — These single-use cameras were able to snap a photo one ten-millionth of a second after detonation from about seven miles away, with an exposure time of as little as ten nanoseconds. At that instant, a typical fireball had already reached about 100 feet in diameter, with temperatures three times hotter than the surface of the sun.

I've noticed that Atomic Bomb subjects appear on dig quite frequently. They usually get a lot of attention, thus the high digg count. For that reason I am posting this comment: If you have any interest AT ALL about nuclear bombs, or want to understand them better, all you have to do is watch the movie Trinity and Beyond: Atomic Bomb (1995). People always talk about this movie in reference to atomic testing, and it's for good reason. This movie is a true eye opener. It's very hard to believe so many tests were conducted, filmed, and studied. Especially interesting were the underwater and atmospheric tests conducted at Bikini Atoll. There is a good 1/2 hour of the movie dedicated to showing these tests. Really amazing stuff. Like I said, if you have any interest in Atomic testing (read: two hours of mindless nuclear explosions) you really owe it to yourself to watch this outstanding film. Not only will you learn more about the subject, you be absolutely blown away by the visuals. (edit: no pun intended, really) (PS. I also want to note here how much of an eye opener this from an environmental standpoint. Seriously, after watching hundreds of explosions just from USA testing (never mind the thousands more from China, Soviets....etc) you will say "Holy F! We totally raped planet earth. No wonder so many people have cancer" or something along those lines. )Link to movie: <a class="user" href="http://www.netflix.com/MovieDisplay?movieid=20767131&trkid=189530&strkid=20998963_2_0">http://www.netflix.com/MovieDisplay?movieid=20767131&trkid=189530&strkid=20998963_2_0</a>"This amazing film chronicles the history of the design, production and testing of the atomic and hydrogen bombs by the United States.

Buelldozer, no. The article clearly says the delay after detonation before exposure (trigger time) was 1 ten-millionth of a second, and the exposure time (shutter speed) was 10 nanoseconds. Read it again.

afbase, I wasn't talking about shutter speed, although that's even more impressive at 10 nanoseconds, which is way faster than 10 microseconds. I'm simply pointing out that the article says the time between detonation and exposure is 10 microseconds, which means the detonation happens and 10 microseconds later the shutter opens for 10 nanoseconds. If the camera is 7 miles away, the light hasn't has time to travel that distance in 10 microseconds, so there must either be something incorrect with the numbers or the description of the delay time.

I've never seen a comment with that many negative diggs before. Congratulations.
