If you tried to use an old fashioned camera under water, you would most likely ruin the camera and not get any pictures. Since the invention of digital cameras an increasing number of people have used underwater cameras to take pictures of marine life. A fish camera allows fishermen to see where the shoals of fish are most likely to be as they have a better chance of taking home the catch of the day.

There are different types of underwater cameras and the most sophisticated models will do a lot more than the cheaper ones. If you just want to try out an underwater camera next time you're on vacation, why not get one of the new disposable ones? You can always get a non-disposable camera later if you enjoy filming underwater. While a disposable camera is okay, several feet under water the pictures may not be as clear as with a regular underwater camera and you may get blurred or dark pictures because the lighting capacity is not so good.

The design of these cameras has advanced so that you can now get affordable underwater video cameras to make an underwater film that you can enjoy later. Cameras that can be used under water are extremely useful for the professional fishermen who makes major catches because they can be alerted as to when the stock of a particular type of fish is low.

It's all too easy for the bays' to become over fished and underwater cameras means that fishermen can keep their finger on the pulse of marine life and know when it's still ok to fish in certain waters and not to fish in others.

If you plan on making filming a regular hobby, it might be an idea to get one of the mid range underwater camera kits as it will give you more flexibility with your filming. You do need to take care of this camera if you want it to last a while and take good pictures.

When you've been on a trip you should always rinse your camera off with clean water to prevent corrosion. Make sure that the camera is thoroughly dry before you open it as you don't want any of the water to drip into the camera.

When you dive into the water it's a good idea to have a lens protector on your camera, if the lens gets broken you'll have a ruined lens and possibly a broken camera. If there is something wrong with your camera, you should get it looked at by someone who is qualified in dealing with underwater cameras. Most cameras and camera kits will come with a warranty, covering parts and labor for a specified period.

Every time you need to open your camera you should check for dirt, as any hard particles can let water pass the O ring and get into the camera. If the O ring is broken it will have to be replaced before you can take the camera under water again.

Also, if your camera is not going to be used for a few weeks you should remove the batteries to prevent them leaking throughout.
