The art of underwater photography is only carried out using special marine digital cameras operated by professionals from many scientific disciplines. Using an marine camera requires skill as you are operating in a foreign environment Many waterproof cameras are ok but they cannot be submerged for more than a meter below the surface of the water
Buying one of those marine digital cameras isn't really likely but you could buy one of the cheaper options if you are only going below the surface for a short while and not to deep.
You see, water pressure is the real problem for these cameras as well as water leaks Of course quality camera manufacturers have overcome this problem by creating watertight plastic cases that encompass the digital camera. Cases like this, inexpensive in comparison to a real marine digital camera, can for a while make you believe that you too are some kind of underwater photographer.
If you are shooting with your marine digital camera, you need to take note of a few things to help you come up with the best underwater images.
Water diffuses the light and the farther down you go the more this diffusion occurs. The result of this is a darkening of the captured image so adjustments to the white balance are needed. You will also notice when you see the pictures taken underwater that they appear larger than they should; this is part of the magnifying effect water has. You will have to pay more attention using the viewfinder to make sure you are achieving the shot you want.
It is not uncommon for waterproof case to spring a leak so before you go on your dive, check that the camera I still watertight by submerging it for a couple of seconds. It is quite easy for something as tiny as a human hair to break the camera case seal and this will lead to a leak. Small silica gel packs can be useful if they can fit in the case without causing an obstruction.
Optional lenses are often available so if you can add these to your marine digital camera then do so. Lenses that allow you to get really close to the subject can also normally be fitted jus ask if the camera has a macro facility.
When you have finished using your marine digital camera be careful to wash it thoroughly to make sure all the salt water is removed as the salt will crystallize and this can cause leaks. The best way to rinse of an marine digital camera where grains of sand are present in particular is with a flow of clean water.
