Many waterproof digital cameras are not just used to capture underwater memories; some professional marine photographers also use underwater digital cameras in their business. The likes of marine biologists and other scientific personnel use underwater digital cameras to study life beneath the waves. You see there are very few genuine underwater digital cameras as it is such a specialized area.
In fact the only way you are really going to get to use an underwater digital camera is if you buy one of these small specialist cameras that are able to be submerged for short periods.
There are very few true underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure so you often have to settle for buying the best waterproof digital cameras. 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 underwater digital camera.
There are a few things you need to be aware of if you are taking photos underwater. First buy a waterproof or underwater digital camera. And then periodically check for leaks in the casing.
Remember that as you farther down you go underwater, the more the light diffuses. The result of this is a darkening of the captured image so adjustments to the white balance are needed. The water also has a strange effect on how the pictures look giving them the appearance of being magnified. Be sure to check your underwater digital camera's viewfinder to check the right picture angle and size that you want.
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. It has not been unknown for a grain for sand to be breaking the seal on the case which will allow water to access the case so look for this as well. To help combat any condensation, place a silica gel pack or two inside the camera case carefully making sure the camera will still work.
Don't be afraid to experiment with your underwater digital camera by adding other lenses that may come with it. The likes of macro lenses will allow to take close up pictures for example.
Make sure when you re-surface that you rinse off the camera full to make sure all the salt water is washed off the camera as crystals of salt can break the camera seals. It is not uncommon to experience the odd grain of sand getting into the case which will cause problems later on so rinse the case with a flow of clean water.
Manufacturers who can supply this type of equipment are Sony, canon and Nikon, so to find out more log onto their web sites.
