What is femto-photography? To be able to capture how waves of light propagate in space, one would need to build a camera that is able to take one trillion frames per second. At first, this sounds impossible, but researchers at MIT and the University of Zaragoza have managed to crack this nut: in their newest work they published to SIGGRAPH that they call femto-photography, we can observe how a mirror lights up with its image as light propagates from the light source to the camera. All this in slow motion!
