The only people I have seen use proper underwater digital cameras are marine botanists and other scientific personnel Marine biologists and scientists use underwater digital cameras to capture marine life and thus are able to study the life and properties of marine life.

Buying one of those underwater 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 Some of you may have seen or tried the cheap solution to this problem that comes in the form of a plastic casing. As a make-do, it woks quite well; converting an ordinary digital camera into an underwater camera.

As this is a completely different area to normal photography you would be well

Light distorts or diffuses underwater an effect that is made worse at greater depth. direct result of diffusion; a problem that can be overcome by changing the white balance settings. 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 a good idea to make sure that the camera won’t leak whilst you are diving so just hold it under the water for a few seconds to be on the safe side. 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.

If you have a chance you should try and fit additional lenses if at all possible to your underwater digital camera to increase the type of images you can take. It is possible to get really close to some subject for great close-up shots using a macro lens.

Also, remember to always wash of salt when you’ve used it under salt water because if the salts are not washed off, in time they will crystallize; and cause leaks in your camera case. In cases when sand seems to get into the case, it is best washed off with streams of water.

You will find out more about underwater digital cameras at the Sony, canon or Nikon web site who are manufacturers that produce this type of specialized item.
