Water Proof Cameras
The art of underwater photography is only carried out using special underwater digital cameras operated by professionals from many scientific disciplines. Studying the life below the surface, underwater digital cameras are only normally within the realm of marine biologists and other nautical scientists To be waterproof is to resist the water to certain levels, submerging it under the water to get the perfect shot is like throwing it out of the window expecting a pick-up truck to pass by and run over it.
The only way you are going to come close to taking proper underwater shots is by purchasing one of those little disposable units that can be used safely for about 50cm to 1 meter underwater.
There aren?t that many manufacturers of these specialist cameras owing to the problem of water ingress into the cameras case and the pressure they have to work under. The closest electronics has ever got to producing underwater digital cameras are producing underwater casings for digital cameras. These cases have been very popular, especially with people on holiday that want to take a few underwater snaps with their favorite digital camera.
If you are shooting with your underwater digital camera, you need to take note of a few things to help you come up with the best underwater images.
Remember that as you farther down you go underwater, the more the light diffuses. 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. Use the cameras viewfinder to check that what you want in the image is actually in the viewfinder or the shot will be wasted.
On the subject of checks prior to going underwater, it is a good idea to make sure the digital camera case doesn?t leak so submerge it underwater for a short while just to confirm it will be ok when you dive. Especially check the seal to make sure that a grain of sand or even a hair hasn?t broken the seal. 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. If you enjoy looking at things close up then you will need to fit a macro lens.
When you have finished using your underwater 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. In cases when sand seems to get into the case, it is best washed off with streams of water.
It is usually the better digital camera manufacturers that will manufacture the more specialized products like Nikon, Canon and Sony
