“My goal is to tell the story of the dog I am photographing, and this particular dog, Buster the Cavalier King Charles Spaniel (above), decided to turn our “on-land” photo shoot into an 'in-the-pool' shoot when he started jumping in over and over again in pursuit of his favorite tennis ball,” says Casteel. “I left, bought a little point-and-shoot underwater camera, zipped back and jumped in. The resulting photos were the beginning of my series of underwater dogs."Picture: Seth Casteel, Underwater Dogs
