The Special Marine Digital Camera

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

Now if you're really serious about using an marine digital camera to capture those wacky and funny moments underwater, I suggest that you buy a specialty camera.

There is lack of real marine cameras owing to the problems of water ingress in to the camera and of water pressure Manufacturers have found it is easier just design a watertight case that goes around the digital camera instead. This type of casing will turn your conventional digital camera into an marine digital camera.

There are a few things you need to be aware of if you are taking photos underwater.

The water has a strange effect on light as I am sure you have experienced from time to time; it is called diffusion and the deeper you dive the more this distortion takes place. direct result of diffusion; a problem that can be overcome by changing the white balance settings. This diffusion effect also magnifies the image to give the impression the zoom function was used. To ensure the correct image will be taken you will have to pay a little more attention to the shot you are taking.

You don't want to have a camera that leaks when you go underwater so before you dive, check that the case is waterproof by holding it below the surface for a few seconds. Especially check the seal to make sure that a grain of sand or even a hair hasn't broken the seal. 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. It is possible to get really close to some subject for great close-up shots using a macro lens.

The seals on the marine digital camera need to be kept clean and free fro contaminants so ensure the camera is thoroughly rinsed of when you return to the surface. In particular where sand is present then a stream of water to rinse it off is best.
