There are a variety of different cameras that have been specifically designed for use underwater, or in environments where they are likely to get wet. Choosing which one to buy is a matter of considering your requirements, as well as the cost of the different types.
Some disposable cameras can be used in the water. These are very cheap and usually take twenty to thirty photos. Once full, the camera is handed over to be developed and cannot be used again. These camera are usually suitable for use in wet conditions, such as rain, snow or when splashing around at the beach. They can generally cope with being taken underwater to a depth of 20-30 feet, which makes them ideal for a snorkeling or diving trip.
Reusable cameras are also available for underwater use, and they will be a more sensible option for those who often require a waterproof camera. They can usually be taken into more deeper water than their disposable counterparts. Film cameras that are designed for underwater use can be found at quite low prices.
A range of underwater digital camera is also available, with many different models offering various levels of quality and cost. Many have excellent resolutions that will ensure a detailed, high quality photo. They are designed to be simple to use when underwater, and can usually be switched between land and sea modes with a one-button click.
Many cameras offer additional options, such as a range of flash modes specifically tailored for different undersea conditions; each intended for use with different types of subjects at different distances from the photographer. The more advanced users will be able to find cameras that offer a selection of manual controls for resolution, exposure and other settings.
In order to get a true picture of the bright underwater colors found in many dive sites, it is possible to add an external flash to the camera, which will provide much more light than the camera's inbuilt flash, and can allow the subject to be lit from different angles. Digital cameras have a specific mode for use with a different flash.
When taking photographs underwater it is important to be aware of the differences in the light, as opposed to above water photography. The light grows dimmer with increasing depth, but many cameras will be able to compensate for this automatically by changing the aperture and shutter speed.
Choosing a model with a large, clear picture-viewing screen will make it easier to set up your underwater pictures; although some photographers prefer to use a Sports Finder mounted on top of the camera. If you will be underwater for quite a long time, and need to conserve power, then shutting the screen off may be necessary. Having a large one mounted on top of the camera can make this easier.
