Choosing A Digital Camera For Underwater Photography
The underwater world is full of wonderful serene scenes making us wonder at nature and why species bothered evolving out of the sea. Seeing its beauty is one thing, but capturing it on camera can be tough. Well, not really. The pictures above, for example, are not fancy commercial photos, but rather amateur shots using budget Sealife gear. There are two routs really to shooting underwater - getting yourself a waterproof digital camera or waterproof casing for your current model. Pros and the unevitable cons of both are underlined below.
Waterproof Cameras
These are specifically built cameras for underwater photography. There are no fiddly casings to mess with, the camera is ready for the dive, but on the flip side it is not that great on land. The Sealife Reefmaster pictured below is a great little waterproof digital camera with a depth rating of 40m and is perfect for all those expeditions to the beach or sea.
Waterproof Camera Casings
Alternatively, if you have a digital camera that you prefer and love, you can buy a waterproof casing for it to take it diving with you. This housing provides rubbery waterproofness typically down to 40 metres and easy to use big bright buttons. On the downside, you can always forget to pack your casing when going away, plus they’re not suited to more serious depths, but apart from that they should help you have all the fun a dedicated waterproof camera would.
Loss of Picture Quality Underwater And The Use Of Flash
A big problem that underwater photographers face, apart from unfriendly marine life and wild hairdos, is the extreme loss of colour and contrast at depth. This is due to colours such as red and orange being easily absorbed by water, which is why the sea appears so blue and green.
One way to solve this is to cut the distance to your subject, ideally to under one metre, as this will minimise the colour loss. You can even use wide angle lenses to get really close. Another way is to use flash, either your built-in one or a dedicated off-camera unit, which will fill-in the scene with a full spectrum of colour.
