Five of camera man Doug Allan's most memorable wildlife encounters

THE wildlife cameraman Doug Allan was described by David Attenborough “as the toughest in the business”. Aged 65, he has filmed an extraordinary range of animals, including snow leopards in the Himalayas, orcas attacking gray whales off California and a pod of killer whales working together to kill a seal.
To get his shots, he has endured temperatures of minus 55C. He has had to dive to depths of 75m under ice and risked the dangers of upsetting white sharks, wolf packs and an attack by a walrus.
