1. Nicklin forgot the tip about giving sufficient space to the wildlife. When he took a photo of the leopard seal, he thought the seal was going to attack him. He did remember to set a fast shutter as the leopard seal would swim away quickly.
2. The photographer created hope for the elephants. His photos show the elephants living in a sanctuary after all the years being threatened by poachers. So there is hope that elephants can survive. It is something that can only be learned out in the wild as the feeling must come from your heart through direct contacts with the animal.
