Can I buy An Underwater Digital Camera?

By Owen Jones


Do you enjoy swimming, scuba diving or snorkeling in the sea or fresh water? If you do, then I am certain that you have seen some lovely 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 small one.

Anyway, going back to swimming. There is a method of taking photos underwater, as you well know, but what you might not know is that underwater digital cameras are not as expensive as you probably think.

The first thing to realize about underwater digital cameras is that not every underwater camera is the same. You probably expected that, but what I mean is that underwater digital cameras are like waterproof watches.

Some watches are waterproof to 10 feet, others to 30 feet and others to 30 fathoms. The same is the case of underwater cameras.

If you want to save money when buying an underwater digital camera, purchase one that will operate a couple of fathoms below where you are going to use it.. A fathom is six feet, so if you are a free swimmer or even a snorkeler, you probably will not go far 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 fairly standard camera encased in a waterproof and pressure resistant casing. The camera is attached to external buttons by wires and these buttons work the camera from outside the casing.

A camera and its casing or housing like this costs about $250 and is guaranteed to be waterproof to about 180 feet or 30 fathoms. This is a lot deeper than 99% of unassisted swimmers ever go in their entire lives. In fact, most scuba divers hardly ever go deeper than 30 fathoms either.

When you use an underwater digital camera you have to remember that the lighting underwater is not as bright as it is above water. Therefore, the settings on your camera ought to 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 changing 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 be truly disappointed when you come to use it for real. A couple of tips are to prevent the casing and the lens from steaming up.

Rub some spittle on the front glass and the camera lens, just as divers do with their mask and put a few packs of silica gel in the casing to soak up the humidity.

If you are a keen swimmer and a keen photographer, price is no longer a real barrier stopping you from taking beautiful underwater shots of what you see with an underwater digital camera.
