Donald Miralle's 2006 shot of Olympian kayaker Scott Shipley training in Charlotte, North Carolina, was triggered by a Pocket Wizard transmitter attached to Shipley's chest. "This was a photo I spent much time conceptualizing and preparing for," Miralle recalls. "But sometimes it's better to be lucky than good." He used a Canon EOS-1DS Mark II with a 15mm lens in an underwater housing. ©Donald Miralle/Getty Images
