Underwater Photography

I am often asked how I make my Swimmer prints. Here are some of the photos from the underwater shoots:

I use my Nikon D3s camera in the pool, with a 20mm lens. I use an Outex waterproof housing, as seen in one of the photos below. I use breatholding techniques fins and a 5 kilo weight on a weightbelt so that I can easily stay down underwater while photographing the swimmers.
