Underwater Photography Glossary

Technically super macro refers to larger than life images that are captured at a magnification greater than 1:1. Digital cameras have complicated what that definition means, the currently accepted definition of a supermacro image is one that captures an area no larger than 36 x 24mm (1.4 x 0.94 inches -- the size of a 35mm slide). You'll need extra focal length and magnification to accomplish this specialized form of imagery. In addition to a standard long focal length macro lens (see "macro"), you'll need to add one of three options: a teleconverter, screw on diopter or wet diopter. It helps to also have good eyesight, stable hands, perfect buoyancy and patience.
