When a bullet hits a steel wall.

Ultra high speed photography is amazing.

Epic.

The uniformity of the disintegration as a result (I presume) of the weakening of the bullets structure by the striations is pretty impressive, and would indicate a fairly close to 90 degree angle of impact.

That must have taken days to set up :)

Well you can see from the marks that they did try it before.

The amazing thing (in my mind) is that was shot at over 1 million frames per second.

Obviously, no shutter mechanism can move that fast, so other techniques have to be used.
One's first thought would be "electronic", but this frame rate has been achieved with special film and a rotating mirror mechanism around 1940. It was used during the Manhattan Project.

The CMOS electronic sensor broke the 1 million FPS record in August 2011, but, as with all achievements, the desire to exceed was kindled.

It wasn't long before researchers at MIT, had developed a camera that can capture 1 Trillion frames per second.

A brief intro is here: http://www.wired.com...ng-light-waves/


If, like most of us, you are content with a paltry 1 million FPS for your home video, the camera for you can be found here: http://www.visionres...d-Cameras/v121/

I don't even want to know how expensive that camera is.

It's simply going to make me cry.

Get your tissues ready ...... :)





The cost, to have and to hold, is currently $118 000.

However, there might be a price reduction, since the Phantom HD Gold has now been released.

This new baby can image at a rate of 1.4 million FPS.

I remember how chuffed I was when my ability for high speed imaging was improved such that I can capture an image at 0.0000312 of a second. (1/32000)

This is achieved via a Sigma EF500 Super strobe.
