A photo shoot usually requires a photographer to just point a camera and snap - but U.S. artist Alan Sailer takes the process much more literally. The California-based photographer, 54, has captured a series of otherwise unassuming items as they explode on contact with a bullet. The dramatic results feature everything from flowers to fruit, as well as more unexpected items such as bacon and even snow globes.
An expert at high-speed photography, Mr Sailer takes the pictures in a dark room positioned around 20cm from the target. The camera, which features a unique home-made flash, is set at a one-second delay. Mr Sailer, who describes the process as 'beyond dangerous, says: 'The special item is the flash. It is a home-built unit based on the design of Harold Edgerton*. The flash is about .5 microsecond in duration and runs at 17,000 volts. It is beyond dangerous, it's deadly.
'The flash is triggered when the pellet from a rifle travelling at about 200 metres per seconds passes through a laser beam. Its the same principle as those beams that set off a chime when you walk into a store,' he continues. 'The camera is set at one second and an f-stop of 9-13 depending on the reflectivity of the subject. The flash stops the action. The one second gives me time to click the camera shutter with one hand while I pull the trigger on the rifle with the other.'

MIT's trillion frames per second light camera
13 December 2011
A camera capable of visualising the movement of light has been unveiled by a team of scientists in the US. The equipment captures images at a rate of roughly a trillion frames per second - or about 40 billion times faster than a UK television camera. Direct recording of light is impossible at that speed, so the camera takes millions of repeated scans to recreate each image.
The team said the technique could be used to understand ultra fast processes. The images have been turned into films lasting roughly 480 frames. This footage shows different wavelengths of light rippling over the surface of a tomato.

Popcorn
I wish they'd just filmed the subject with the cool sounds. Who uses olive oil for popcorn anyway? twats, that's who!
You can watch in full HD though, so that's good
