Nachoum spent 45 minutes with the polar bear family, slowly gaining their trust and understanding their movements before taking the big plunge with them into the water. He was able to capture the heartening moment when a mother bear taught her baby cubs how to swim as they searched for food together. Nachoum and his team spent about three to four hours with the bears as they swam from island to island. The polar bears mostly went about their business without paying much attention to Nachoum and his crew.
Nachoum said the secret behind successfully photographing the bears was staying in the mother's line of vision at all times.
"We weren't making any aggressive moves or moving toward her," Nachoum said. "She always knew where we were and that meant to her that she's safe, that we're not crossing the line. One of the babies actually went down to look at me, came close as three feet away, and then went back to the surface."
