High speed photography of transient phenomena
Freezing fast motion (AKA High Speed Photography)

MIT professor Harold “Doc” Edgerton figured out how to marry a still camera and a strobe light that could flash up to 120 times a second, stopping time and allowing for the analysis of events too fast for the naked eye to see, like a bullet passing through an apple or a drop of milk splashing down (below). Using stroboscopic photography, Edgerton’s cameras also enabled the Allies to take nighttime reconnaissance photos from airplanes during World War II and photographed atomic bomb tests from miles away.

Experiment with Action shots Tv (Time value) shutter –priority on the mode dial.
* to freeze action use a fast shutter speed such as 1/500sec. to 1/4000 sec.
* to blur action (for a running child or animal) use a medium shutter speed such as 1/60 sec. or
to blur (a flowing river or water fountain) use a slow shutter speed such as 1/5 sec to 1/15 sec using a tripod.
