This is a fascinating look behind the scenes of the work of photographer Richard Mosse.
He used a decades-old film format that reads infrared waves to take photographs and record on film in the Congo.
The film was developed for use in combat. It allows soldiers to see past camouflage and spot enemies hiding in vegetation.
The result is an eery, pink landscape populated with soldiers striking macho poses. The work makes us question how color impacts our view of events. Are these pink photos and video more or less real than black and white?
