If you are buying a new underwater camera or video camera, you will need an underwater camera case. And this case needs to be watertight, airtight, dustproof, crush resistant and designed to keep your valuable equipment safe from all the elements. It may also be rustproof, pest-proof, and chemical resistant to oils, fuels and solvents. It may have flame retardant included and be molded with a UV stabilizer, making it ultraviolet resistant. (This will prevent the plastic from becoming brittle if left in the sun for extended periods of time.)

There's so much you can do with an underwater video camera. If you enjoy snorkeling or diving, you can use the camera to show your friends and family the beautiful tropical fish, colorful coral reefs, and other underwater treasures you encountered on your vacation.

But that isn't all. Videotape the children (and adults) swimming at the ocean, lake or pool. This could help them improve their swimming techniques or record their very first swim. Or you could plant your underwater video camera on the bottom of your pool and enjoy all the underwater swimming and games played on the VCR.

Liveaboard scuba diving boats are for divers who just want to dive and nothing more. They don't care about shopping, watching TV in a hotel room or site seeing other than beautiful coral reef.

Liveaboards come in all kinds of shapes and sizes. They are built to serve as hotel, restaurant, dive shop and sometimes even a photo lab all in one package.

Patience is a virtue. It always has been and always will. In photography terms, it is vital.

We are so used to things happening rapidly in photography that we can sometimes feel overwhelmed and ever ready for the sudden shot or opportunity. Candids, objects going at breakneck speed and the general rush of life all make us believe that getting the correct shot “as soon as possible” is the only way to capture a great image.

No so. Take your time, relax and chill out.

There will be times that you need to act quickly. But in more cases there is a need for patience and perseverance.

A debate that could rage on for eternity, but let’s look at the basics. Every photographer has their own unique style, developed over time and moulded by their background and personality. Some photographers stick religiously to black & white images, whilst others swear by full colour. Which is right? The question to ask though is which is right for the individual image.

You can get some great images using your camera underwater. Think about the following to ensure you don't miss that important shot:

Get an underwater housing - most cameras can be fitted with a specialised, waterproof underwater housing. These are available from specialised retailers or from online auction sites.

Think about an underwater camera - this is specifically designed to be moisture-proof and sustain the rigors of immersion in water

Having the sun overhead (that is around either side of midday) gives the best results underwater

Very few entertainment opportunities can provide as much variety and enjoyment as scuba diving. The opportunity to view underwater life is one of the most revered experiences in the world. Probably one of the biggest lures of scuba diving is how the entire family can enjoy it. Children and adults can both enjoy scuba diving. This one aspect of scuba diving has made it one of the many options that people choose to do on family vacations.

Scuba diving dry suits are for diving in cold water settings and they only come in one type of style: full length arms and legs. The only difference among the different brands of dry suits on the market are in the materials used to create the suit and the placement of the zippers.

Dry suits maintain warmth by surrounding the scuba diver with a layer of warm air trapped in the clothing worn under the dry suit. As the scuba diver decends in the water, the air that is in the suit compresses, but the pressure can be equalized by the use of a low pressure hose connected to the divers air supply.
