Technology and Advances in Photography: Shutter Speed

Photography enthusiasts know that one of key control parameters in photography is shutter speed. The others being aperture, ISO speed and to a lesser extent, white balance.
Ever since electronics based automation entered into photography in late 1980's there have been steady advances. With the advent of digital cameras and DSLR's in the 21st century, the advances have been breathtaking. But what about advances in shutter speed? Some of the top of the line cameras in 1990's had a top speed of about 1/2000 sec. Some of the top of the line professional DSLRs now, like Canon EOS 1DX, has a top shutter speed of 1/8000 sec. Cameras like this are sports photographer's best friends.

But what can you with a camera that has a top shutter speed of trillionth of a second? You can capture the movement of a single photon of light, of course !!! This is exactly what MIT has built. Take a look at this: MIT Built Camera that can capture video at speed of light

What do you think?
