In the basement of National Geographic’s headquarters, there’s a lab holding a secret tech weapon: Tom O’Brien. As Nat Geo’s photo engineer, O’Brien adapts new technologies to capture sights and sounds previously never seen or heard before. In this episode, originally published in June 2021, O’Brien leads us on a tour of his lab as he designs and builds an underwater camera and shows us some of his favorite gadgets—including a camera lens that flew over Machu Picchu in a blimp, a remote camera he designed for the film Free Solo, and a piece of gear known simply as the “funky bird train.” For more information on this episode, visit natgeo.com/overheard. Want more? See National Geographic's Pictures of the Year and our five picks for Photographers of the Year. To capture one of the year's best pictures—an encounter with elephants in Gabon—O'Brien outfitted a photographer with 1,100 pounds of custom gear. Our photographers capture millions of individual frames per year. In a previous episode of Overheard, Nat Geo's deputy director of photography breaks down the process to select only the best images. See photographs mentioned in this episode, including wolves captured by a gnaw-proof camera, sage grouse as seen by the funky bird train, and a cheetah running in super slow motion.
