After a quarter century of traveling the world on amazing assignments for National Geographic, I'm still learning how to take nonfiction photographs that say more. What underpins my photographs for National Geographic? Pencil-blunting research long before a shoot. On-the-fly camera settings and in-the-field improvisations. And sometimes I just get lucky. Mostly, I never take myself too seriously and I always figure there must be a better way—if I can just figure it out. Learn with me as I keep growing.
