Ramesh Raskar

MIT professor Ramesh Raskar starts his talk by showing the classic Doc Edgerton photograph of an apple being shot by a bullet. It demonstrated an exposure of a millionth of a second.

Only now, 50 years later, technology advances mean we can photograph a million times faster than this. “Now we can see the world at a trillion frames per second,” he says. “I present to you femto-photography, a new imaging technique so fast that it can create slow-motion videos of light in motion.”
