Photo: One Ocean One Breath

The husband and wife duo of Eusebio and Christina Saenz de Santamaria have set freediving records all over the world. Eusebio is one of few men to have reached below 100 meters under his own power, and Christina recorded the deepest self-powered dive of any Australian woman at 85 meters. Possibly more impressive than their diving skills is the pair’s photography, which they’ve made into a business under One Ocean One Breath . Based in Koh Tao, Thailand, the couple captures dazzling underwater scenes as they train and dive in some of the world’s most vibrant oceans. Here, the couple tells us about a few of their favorite shots.One of our favorite images of all time is of Eusebio kneeling on the grassy sea floor as a Caribbean reef shark cruises by. The crystal clear waters of the Caribbean allow for this type of creative black and white photography, which we like to use as a way to express the surreal and magical world we experience—an otherworld where sharks can fly.
