1. Before a career in photography, Clark surfed. 2. I like seeing water photographed, as water is very hard to mold, so you have to capture it in the moment. 3. It's very monotonous, and not much variety other than different ways of photographing said water. 4. Nikon D4S, using waterproof housings so he could photograph in water environments. 5. I think that the ocean is meant to be seen every once in a while as a vacation, I wouldn't want to go there most days of my life.
