Pl umb the depths
The underwater world provides unique challenges, but the results can be worth the effort. Custom housings – costing upwards of £1000/$1500 and offering shooting at depths up to 100 metres – are available from specialist retailers such as Cameras Underwater. Alternatively, a basic Ewa Marine U-A universal waterproof casing will set you back around £200/$400, and can be submerged to 20 metres. This depth allows for the experimental paddler and recreational diver to combine their hobby with photography. Rental is also available.
Underwater photography will test the low-light capabilities of your D-SLR, so a fast wide-angle lens and extra lighting are helpful or, failing that, shooting on a sunny day near the surface. Even a stream can provide interesting results.
