Underwater Photography By David Doubilet

Photographic Career
His goal as a photographer is to "redefine photographic boundaries" every time he enters the water. This has helped him achieve some of his greatest shots. In order to capture all the underwater wildlife, he takes several cameras with him on each of his trips. The main obstacle in underwater photography is the impossibility of changing lenses or film underwater.
Doubilet’s ingenuity lead him to the invention of the split lens camera. This allowed him to take pictures above and below water simultaneously. This worked by having a separate focus point on the top half and bottom half of the scene. When the picture is taken, it is recorded onto the same negative.
