In a mind bending study of numbers, Yvonne Bang of Nautilus magazine details precisely how far photography has come since the days of eight hour development times. The findings are not based on consumer cameras, but rather laser based image-making devices used by scientists. 

"Today, we can capture photos with an exposure time of a trillionth of a second, and are at the brink of attosecond photography—that is, snapshots taken 10 billion trillion times faster than those first grainy images in the east of France." 

This had me wondering what on earth an attosecond is. The short answer is pronounced "one quintillionth of a second". Wikipedia takes it a step further, noting that "an attosecond is to a second what a second is to about 31.71 billion years." Read the entire piece here

For those you who, like me, prefer visual examples, here is an amazing video which includes footage of a "Laser pulse shooting through a bottle and visualized at a trillion frames per second".
