In wildlife photography, understanding the behavior of your subject is critical. By way of example, professional wildlife photographer Zac Mills takes you to an Indonesian rainforest where he photographs the orangutan. He finds that the best time to photograph these solitary creatures is early in the morning after they emerge from the nests they built the night before. He learns that a baby orangutan will stay with its mother for seven years until it learns about survival in the forest. Zac shows you his wonderful images of orangutans alone and with their children. To capture your own wildlife images, there is a visual payoff in knowing your subject.
