They film the firings from multiple angles at high speed so they can go frame-by-frame and assess the effectiveness of the muzzle break, the speed of recoil, and how the components flex under the stress of firing, among other things. <br /> <br />They get data, we get cool pictures!<br /><br />John of Argghhh!<br />(www.thedonovan.com)Chuck Pergielhttps://www.blogger.com/profile/14473338620167201696noreply@blogger.comtag:blogger.com,1999:blog-4261262990290532740.post-17855532389312440432009-05-25T23:01:54.200-07:002009-05-25T23:01:54.200-07:00I dunno.

Casio has a high speed camera (http://pergelatorlite.blogspot.com/2008/05/electronic-do-dad-delay.html) that can take 1200 fps.<br /><br />These guys (http://www.visionresearch.com/) have a camera with a one microsecond shutter speed.Chuck Pergielhttps://www.blogger.com/profile/14473338620167201696noreply@blogger.comtag:blogger.com,1999:blog-4261262990290532740.post-31099981917044778672009-05-25T20:44:43.256-07:002009-05-25T20:44:43.256-07:00Assume the bullet is going at mach 3.

That's 3000 feet per second.<br />So even with a 1 millisec exposure time, it would have moved 3 feet, which is comparable with its own length, so the photo would be blurred.<br /><br />therefore likely to be photoshopped.Anonymousnoreply@blogger.com
