My Simple Advice For Using Cameras
By Busy Door Guest Blogger | February 17, 2009
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.
Now if you’re really serious about using an underwater digital camera to capture those wacky and funny moments underwater, I suggest that you buy a specialty camera.
There is lack of real underwater cameras owing to the problems of water ingress in to the camera and of water pressure. 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 or waterproof camera.
As this is a completely different area compared to regular photography you should learn some underwater and waterproof digital camera tips as well.
The water has a strange effect on light as I am sure you have experienced from time to time; it is called diffusion and the deeper you dive the more this distortion takes place. The result of this is a darkening of the captured image so adjustments to the white balance are needed. Also, pictures taken underwater will come up larger than pictures taken on land with the same zoom effect. 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. It is quite easy for something as tiny as a human hair to break the camera case seal and this will lead to a leak. If you a couple of silica gel packs then these can be placed in the case but make sure they do not obstruct the lens or camera controls.
Don’t be afraid to experiment with your underwater digital camera by adding other lenses that may come with it. Macro lenses will help you capture small things without getting too close and startling your subject.
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. Sometimes, small grains of sand gain access to the case and in this instance rinsing with water is the most preferable solution.
