Events
which may happen literally 'in the blink of an eye' are the target for
high speed photography. The key is obtaining a very short exposure time,
either by using a very fast shutter or a very short-duration light source.
Fast shutters were used by Muybridge in the 1870s to study animal locomotion,
but required sensitive plates and very bright conditions. Very short
duration flash photography was pioneered by Harold Edgerton in the 1930s,
capturing speeding bullets in flight or freezing milk droplets. However,
the ultimate short exposures, a few billionths of a second, are possible
with pulsed laser illumination.
