MIT Science Reporter—"Underwater Photography" (1964)

This black-and white film features Harold "Doc" Edgerton interviewed by John Fitch about the technology and scientific applications of underwater photography for the MIT Science Reporter (National Education Television, 1964). Edgerton discusses hand-held cameras and deep-sea camera instruments at the MIT Pool, and reviews examples of his underwater photography fieldwork such as searching for the lost THRESHER, and exploring the deep-sea Romanche Trench and Puerto Rico Trench. Edgerton also demonstrates his sonar "pinger" designed to track the towed underwater camera between the seabed and surface ship. The original film is a 16mm film. Courtesy of MIT Museum.
