Amos Nachoum is renowned as a master of photography of big animals – both threatened and endangered worldwide – with the purpose of capturing their behavior. Learn about his awe-inspiring up-close encounters with these ocean giants as he free dives with blue whales off the Eastern Pacific, scuba dives in the Okavango Delta with crocodiles and goes face-to-face with the great white shark. He is one of only five people to ever swim with and photograph a polar bear underwater and the only person to photograph one with her two cubs. More people (only 12) have walked on the moon!
