AN ELECTRONIC DIRECTION INDICATOR FOR DEEP-SEA PHOTOGRAPHY.

Abstract

This report describes a new photographic compass unit for use in magnetic orientation of underwater photographs. The system is of such simple design that it can be fabricated in any laboratory having a small shop and the consultation of an electronics technician. The components of the system are easily obtained in the open market. In essence the small movie camera in the compass unit photographs both the orientation of the compass and the time of the instant that each bottom photograph is taken. The electronic design permits synchronous exposure of the movie and still bottom cameras, and precludes multiple exposures of the direction camera under proper techniques of operation. (Author)
