Underwater films used and the Exposures needed for underwater photography

Underwater Film

The old adage about “walking before you try to run” certainly applies to underwater photography. It might be best for the beginner in this activity to start off with black-and-white work in rather shallow water with natural lighting before attempting deeper picture-taking dives or work with color film or flash gun. Any slow panchromatic black-and-white film should provide prints with good color contrast. For color work, the Eastman Kodak Company makes the following suggestions, which apply equally to comparable film under other trade names:

The use of Kodacolor film has several advantages for underwater color shooting. It has greater exposure latitude than reversal films, such as Kodachrome film or Kodak Ektachrome film. This latitude helps minimize any exposure errors that might be made under the uncertain lighting conditions found under water. Another advantage is that no filters need be used on the camera for correcting the color balance of the film for underwater shooting. Such corrections can be made when a print or transparency is made from the color negative. Kodacolor film is available in sizes to fit almost any camera.

APPROXIMATE EXPOSURES FOR UNDERWATER PHOTOGRAPHY Assuming bright sunlight and light bottom. A dark bottom may require one or two more lens openings; even so, it may cause poorly lighted subjects. Hazy sunlight will usually require at least one-half a lens opening larger.
