NPR: Recently, the New York Times online featured stunning images of atomic bomb explosions, some taken in the 1950s and 1960s by Harold Edgerton, a professor at MIT who developed the rapatronic camera specifically for that purpose. Capturing the explosions was exceptionally challenging, partly because of the extraordinary light intensity and the ultrashort duration. Edgerton, who specialized in stop-motion photography, earned the reputation of being “the man who made time stand still.” While his images reveal what the human eye cannot see, they also achieve a certain visual aesthetic.
