Underwater Digital Camera
Get wet and use an Underwater Digital Camera!
you are thinking about doing some underwater photography, then you will need to do some homework in terms of what equipment you need. First and foremost you will need an underwater digital camera that has been manufactured for use under the water, and at the depth you intend to dive. A water-resistant model is not enough; you need something that can be immersed in water that will withstand the pressure of the water. When you start looking, you will find that different so-called underwater digital camera models can be used at different depths. If you plan to go any deeper than 10 m or 33 ft, it is unlikely that a "waterproof" model will work for you. Instead you will need to find a suitable underwater digital camera that meets your specific needs.
Any model that is designed for use under the water - be it in the sea or in a swimming pool - will have a casing that will protect the workings from both the water and from pressure damage. While there is no film to be damaged by moisture, our new-age cameras that we use in the 21st century rely on electronic circuit boards, and these are quickly damaged (if not destroyed) by water.
Probably the best way to assess a camera that you plan to use under the sea or in water is to read loads of reviews done by professional photographers and experienced amateurs. Weigh up the information they offer carefully, and join blogs so that you can ask lots of questions. It is also helpful to learn what experienced divers think about various cameras, because they know the conditions better than most.
If you can connect with a photographer who has done this type of work, ask about the benefits and the pitfalls of different equipment items. Try to learn from that person's mistakes.
Also be aware that various camera manufacturers offer underwater housings for their products. If this is an attractive option for you, just be sure to find out what the implications are in terms of taking photographs. Chances are you will be able to immerse the equipment in water, but you may not be able to dive with it. However you may be able to snorkel and get some stunning pictures.
The message here is to find out what you are buying before you buy what is advertised as an underwater digital camera.
