The Special Marine Digital Camera

November 14, 2008 by DigitalCamerasInfo 

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 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

Buying one of those marine 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.

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.

Water diffuses the light and the farther down you go the more this diffusion occurs. The result of this is a darkening of the captured image so adjustments to the white balance are needed. 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.

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.

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. 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.
