Some people say that a good photographer can get great shots whatever camera they are using. But sometimes it helps to have a dedicated tool for the job … like the BBCs Penguin-cam.

To help them get close-up footage of Emperor penguins in Antarctica, wildlife producers hid 50 cameras in a series of disguises ranging from rocks and eggs to penguins.

The result is a series of amazing shots which could not have been captured in any other way. Penguins: Spy in the Huddle is being shown on BBC One.
