During David Attenborough's filmmaking career spanning 60 years, there have been unparalleled changes both in the natural world, the understanding of the planet and the techniques used in filming. He takes a very personal journey in this three-part series through the six decades and the massive developments he has witnessed. In episode one, Life on Camera, he looks back on the iconic animal encounters which have shaped his career from the early black-and-white Zooquest days when he had to describe the colour of the animals he filmed, to a close encounter with a lion pride in pitch darkness.
