Underwater Digital Cameras
Taking photos underwater will require a camera that is waterproof and able to function well in the cold water and at depths. Many of the underwater cameras available are shockproof, freeze-proof, include GPS location tagging, Wi-Fi connective and the technology to prevent distortion and reduce camera movement.
Compact and lightweight underwater digital cameras are ideal for travelling and holidays, creating less drag underwater and are able to take videos. It's also means you won't have to worry about splashes when out and about, for example if you go to a waterpark or simply by the pool or sea. The slightly downside is that there can sometimes be an increased shutter and focus delay, the optics are less quality, battery life can be reduced, and less depth of field over an SLR camera which can result in a blurred background. However, the advantages definitely outweigh the negatives, with you being able to capture stunning photographs underwater of either your friends and family or the sea life.
A sturdier build than standard digital cameras , most underwater models are ergonomically-designed, making them on the whole, shock, freeze and crush-proof. Imaging smoothing technology at high ISOs is included, optical zoom lenses provide focal ranges of 28 to 128mm, fast AF performance and optically stabilised to reduce camera movement or shake. A 1cm macro mode focusing distance and bright LCD or OLED monitors make it easier to compose shots, with a quick, reliable autofocusing system and accurate exposure for better picture quality.
Some models have a remote control capability and NFC pairing for easy image sharing and white balance performance improves clarity of the images. WiFi connectivity and GPS system delivers interactive world maps included with altimeter and underwater depth gauges.
Underwater digital cameras are durable, waterproof and are able to function at a high level in depths of up to 30 metres. You can get straps and other camera accessories to ensure you can put it round your wrist particularly when you are in deep waters. However, the underwater cameras are usually made with a type of material that will allow them to float. Of course this does depend by model so check your manual before trying this.
What to look for
When considering an underwater digital camera, ensure that it has a full manual mode function with good quality underwater housing and close macro mode functionality, unless using wet lenses. Ensure a low shutter lag and long battery life with the ability to view histogram and manual white balance. A good auto focus capability underwater will improve images and you should be able to adjust the aperture and shutter speed.
