Abstract
The equipment described was developed for analyzing underwater motion of solid bodies. The experiments demanded a high rate of picture taking and that the subject studied should be in the field of at least two cameras at all times. Edgerton-type flash lamps instead of shutter mechanisms were adapted, an endless film belt giving a one-second exposure was developed, and a film speed of approximately 35 ft per sec used.
