This guide to underwater photography has been written with help and advice from Doug Allan, award-winning underwater and wildlife cameraman, who has spent hundreds of hours filming underwater sequences for the BBC, Discovery Channel, National Geographic and many other channels.
Underwater wildlife and geology films have brought us exciting pictures from an unknown world, and underwater sequences have been used to great effect in many documentaries, television dramas and feature films recording pictures from swimming pools and crystal clear shallow waters to the deepest oceans. Filming underwater is logistically challenging, potentially dangerous and the consequences of getting it wrong can be disastrous (cameras and water don't mix well). But the good news is that there are many cameramen and dive companies who can bring their expertise and experience to your film. With proper planning, research and the right people, your underwater sequence can be achieved with relative ease and fantastic results.
