High Speed Imagery - Harold Eugene Edgerton (aka "Papa Flash")

Harold Eugene "Doc" Edgerton also known as "Papa Flash" was a professor of electrical engineering at MIT (Massachusetts Institute of Technology). Edgerton is largely credited with transforming the stroboscope  to a common device from an obscure laboratory instrument. Along with the stroboscope, he also was largely involved with the development of sonar and deep sea photography, were his equipment was used for searches of shipwrecks.

Edgerton experimented with his equipment by capturing different things from the different stages of a balloon bursting to a bullet impacting an apple. His images of the bursting ballons are taken so fast that you can see the bullet, even though bullets travel at hundreds of feet per second its been captured with such a fast shutter that the bullet looks completely still as if it is floating just after the balloons.

Edgerton's Images of a bullet impacting an apple show the moisture inside the apple exploding out of the entry and exit of where the bullet impacted, showing you in a way how much force there is that the bullet carries. Just like the images with the bullet bursting the balloons, the bullet in the apple images is completely still as well to the point where you can see the details on the bullet itself from where it is held in the casing when it hasn't been fired. Also Edgerton has cleverly held up the apple with another casing from possibly a previously fired bullet.
