Underwater Digital Cameras
http://the-real-way.com
Do you enjoy swimming, scuba diving or snorkeling in the sea or fresh water? If you do, then I am sure that you have seen some beautiful sights. The problem is that, you cannot show them to anyone, can you?
it is that old adage: the things you see when you have not got your camera with you. Which is why professional photographers always have a camera with them, even if it is only a pocket camera.
Anyway, getting back to swimming. There is a method of taking photographs underwater, as you well know, but what you might not know is that underwater digital cameras are not as costly as you almost certainly imagine.
The first thing to comprehend about underwater digital cameras is that not each underwater camera is the same. You almost certainly realized that, but what I mean is that underwater digital cameras are the same as waterproof watches.
Some watches are waterproof to 10 feet, others to 30 feet and others to 30 fathoms. The same is true of underwater cameras.
If you would like to save money when purchasing an underwater digital camera, purchase one that will operate a few fathoms below where you are going to use it.. A fathom is six feet, therefore if you are a free swimmer or even a snorkeler, you almost certainly will not go much deeper than three fathoms or twenty feet. If you are a scuba diver, you will need to spend more.
The easiest and cheapest underwater digital cameras come as a quite standard camera encased in a waterproof and pressure resistant casing. The camera is attached to external buttons by wires and these buttons operate the camera from outside the housing.
A camera and its casing or housing like this costs around $250 and is guaranteed to be waterproof to about 180 feet or 30 fathoms. This is far deeper than 99% of unassisted swimmers ever go in their whole lives. In fact, most scuba divers seldom go deeper than 30 fathoms either.
When you use an underwater digital camera you have to remember that the lighting underwater is not as strong as it is on top of the water. Therefore, the settings on your camera should be such that the lens admits enough light. In order to do this the shutter speed will have to be slower or the aperture larger. These settings can be set automatically by altering the ASA setting.
After you have purchased your underwater digital camera, test it in the bath first to see if the casing leaks otherwise you might get truly disappointed when you come to use it for real. A couple of pointers are to prevent the casing and the lens from steaming up.
Rub some saliva on the front glass and the camera lens, just as divers do with their mask and place a couple of packs of silica gel in the casing to absorb the humidity.
If you are a keen swimmer and a keen photographer, cost is no longer a significant barrier preventing you from taking beautiful underwater shots of what you see with an underwater digital camera.
