Advances in Underwater Color Photography
Use of color films underwater has been limited by lack of adequate light and by red absorption by sea water. Some improvements in equipment and techniques to improve color quality and to enable greater photographable distances are discussed. Two new continuous light sources available for underwater color photography are high-pressure sodium and dysprosium iodide arcs. These sources give four to five times the light output of tungsten bulbs. In order to obtain well-balanced color photographs underwater over a wide range of distances, it is necessary to compensate for the red absorption by water. This is done by filters. The use of the Wratten CCR series is discussed as well as a new continuously variable-density filter that shows promise of greater range of color balance.
