Underwater Digital Camera

When you are in the middle of a dive, you don't get a second chance to photograph the rare stingray, a seal that is cavorting with its mate or some exquisite rainbow colored fish that are hovering in the trail of air bubbles from you mask. An underwater digital camera allows you to immediately see what you have just captured.

It is the best way to capture underwater scenery, corals, fish schools, and anything that catches your eye that you wish to preserve. With an underwater digital camera you can share that special moment forever. You can shoot until you run out of air instead of film. Printing or publishing the pictures on the Internet is very simple, as you need to just connect the camera to a computer and transfer the image files.

Digital underwater cameras allow you to compose the image on the LCD monitor and with a better depth technology, focusing is very easy. Different varieties are available to suit every need. The depth at which the cameras can be used is important. Economical ones can be used up to 5 meters while professional ones can be used at depths of 150 meters or more. Other important factors are: the image resolution, memory, number of pictures you can store, exposure, type of lens, zoom features and many more.

Shooting on land and underwater is different however. At greater depths, the available light becomes faint, diffused and is refracted. Light sources like built-in and external flash allow you to take pictures in faint light. These cameras can be operated in 3 modes - land, sea and external flash mode, which helps take pictures in any under water conditions.

By using external flash you can remove problems like the 'white snow effect' in which light reflects off planktons and sand to create a white fog. It takes some time to master underwater digital photography but since there is no film, you can practice as much as you need. These cameras also have the light balance feature that provides colors, which are better recognized by the human eye. It is possible to pack a digital camera in special, waterproof packs and shoot but this should be done only in case of an emergency.

Underwater photography is recognized as an enthralling profession with many challenges and risks. The advent of underwater digital cameras, however, has made this task simpler and more creative. The photographer can capture more than ever before by using the zoom lens. Underwater digital cameras will take underwater photography to new heights or, should we say, depths.
