"The exposures are at 1/100,000,000ths of a second"
I'm back, did you miss me? What would you shoot at such 1/100,000,000 shutter speed? But of course, perhaps the most spectacular thing possible, an atomic blast! The "first few fractions of an atomic bomb upon detonation". Enjoy http://www.rapidnewswire.com/atom.htm |

The "first few fractions of an atomic bomb upon detonation". For one thing, you need something quite brightly illuminated at that shutter speed -- especially if the T-number of the lens/shutter system used is anywhere near where I think it would be.

There's something about the clean simple form of the fireball at the various early sizes. -- David Dyer-Bennet, , http://www.dd-b.net/dd-b/ RKBA: http://noguns-nomoney.com/ http://www.dd-b.net/carry/ Pics: http://dd-b.lighthunters.net/ http://www.dd-b.net/dd-b/SnapshotAlbum/ Dragaera/Steven Brust: http://dragaera.info/ |

They might have the same college degree I have... Edgerton certainly taught us a great deal about what really happens. Thank you, Doc. -- Frank ess |

What I'm really impressed with is that you were able to zoom back that
quick!! :-) |

The "first few fractions of an atomic bomb upon detonation". Enjoy http://www.rapidnewswire.com/atom.htm I'm not sure how they did those shots, but there have been cameras that have used things like spinning octagonal or multi-sided mirrors that could "flash" exposures across several feet of filmstock in a fraction of a second. For slower (but still fast) shooting, cameras have been equipped with high speed motor winders that took movie film at a high rate of speed, thousands of frames per second. CCDs/CMOS are a problem when it comes to rapid firing as they are limited to their read-out speeds. In order to take images at really high speeds, you need some kind of shutter mechanism. A spinning disk with a hole in it and some kind of synch mechanism. -Rich |

Mechanical devices are orders of magnitude too slow to achieve these results. Repeat of a post to r.p.e.35mm: Alan Browne wrote: Probably a high speed cine camera, eg, 1000's of frames per second with exposure times on the order of 1/4000 to 1/10,000 Exposure time was much less, on the order of ten nanoseconds. Google rapatronic. Each camera took one frame. A starting point: http://simplethinking.com/home/rapat...hotographs.htm -- Andy Williams |

Interesting--I posted a link to these two days ago.
