The people that use genuine marine digital cameras are those where it is usually used in the course of their work as these cameras are very expensive Studying the life below the surface, a marine digital camera is only normally within the realm of marine biologists and other nautical scientists Waterproofing a camera is not an easy thing to do so many, so called, marine cameras aren’t really designed for that type of work
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.
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. This means that your marine digital camera will produce images darker than those images you took while on land so to avoid this, use white balance adjustment to help with natural colors. 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. Many novices make the mistake of not checking the viewfinder carefully to make sure they are going to take a picture containing exactly what they want in the final shot.
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. 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.
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.
