After years of taking pictures of celebrities and athletes, Los Angeles-based photographer Michael Muller turned his attention to creating shark portraits, with astonishing results. In oceans around the world, he approaches the sharks with a seven-bulb, 1200-watt plexi-encased strobe lighting rig, developed with NASA engineering—and no cage. With many of the photos spanning two pages, Muller's images—including the first-known photograph of a great white breaching at night—are arranged geographically, highlighting black tip and sand tiger sharks in South Africa and hammerheads in the Bahamas. Muller makes it look easy, but he also includes thrilling narratives documenting the challenges and near-misses along the way.
