In 1912, Herbert Ponting captured remarkable film and images of Captain Robert Falcon Scott's ill-fated Terra Nova Expedition. Amateurs and pros have all worked to restore and colorize Ponting's work.

The official film record of the British Expedition of 1910-13 led by Scott was reworked by photographer Herbert Ponting to tell the tragic tale but It is the beauty of the images of Antarctica's frozen landscapes in this film that linger.
Bonus: Interesting mini-doc on how they chose the scoring:
The film also shows the "making-of" reverse of Ponting's stunning still, colorized by Imgurian ktrcoyote:
