Cheap Underwater Camera

By John Summerlake


You will find a number of cameras that can be used in aquatic and underwater environments. Camera styles and makes range from specialized digital cameras to less expensive disposable cameras made for underwater use. Knowing a few of the basics of each type of camera can assist you to make a choice concerning a camera in which to invest, whether or not you're a professional or a budding amateur.

Some disposable cameras are made for underwater use. If you're going on a short scuba or snorkeling trip and need something to take the pictures, a cheap, disposable camera will do the trick. Certain things to consider for disposable cameras might consist of dive depth, heat condensation building up from cool waters and warm air environments, and not having a flash. Remember that disposable cameras can't be place through X-ray machines. The majority of disposable underwater cameras can be used at a depth of 50 meters.

You may get a special, rugged version of the disposable camera made with the diver in mind. As opposed to other shockproof, waterproof digital cameras, these diving and sport cameras have specialized dive and snorkel modes to help you get rid of underwater color distortion; rubberized grips on the camera's exterior; and wide-spread controls on the camera body for ease of operation. Manufacturers of these particular dive and sport cameras, such as the Sealife Mini II, also create wide-angle lens attachments and video and flash lights.

One more style of digital cameras are point-and-shoot, non-DSLR models that may be immersed between 10 and 30 feet. There are a number of producers for submersible point-and-shoots, including Olympus, Canon, Pentax, Fuji and Panasonic. These multi-use cameras are typically shockproof, freeze-proof, crush-proof and submersible up to a certain distance or temperature. Many of the recent versions of these cameras also provide high-definition video capabilities and other features, such as carabiner clips, LED illumination, touch screens and face-detection software program.

Specialized cases are made for conventional digital cameras that cannot be submerged underwater. These cases must be sized appropriately for your particular camera model and size. Before every submersion, inspect the O-ring particles for debris, such as hair or sand, that may cause leaks while underwater. Apply a small quantity of water-tight grease on the surface of the O-ring before re-inserting it into the case. Make sure to rinse the case in clean, fresh water after every submersion, making sure that sand along with other debris are clear from buttons and gaskets.
