Eastern Congo, 2011. Photo by Richard Mosse.

An ongoing war in eastern Congo has killed more than 5 million people since it started in the early 1990s. How do you draw attention to an armed conflict the world is largely ignoring? Photographer Richard Mosse spent years in the region documenting combatants with infrared film to make the camouflaged soldiers of the Democratic Republic of Congo stand out rather than blend in with their surroundings. 

Mosse, who last week won the Deutsche Börse Photography Prize for his resulting project 'The Enclave' used discontinued 16mm surveillance film, which renders lush green foliage as bright pink.

The Enclave is a multi-media piece which combines stills and video. The work is displayed on six large double-sided screens installed in a darkened chamber, creating what the artist calls 'a physically immersive experience'.  Slightly more detail about the work is available on Mosse's website.

In the 'making-of' video above, Mosse talks about the collaborative processes with the cinematographers in his group, and how years of covering the conflict in the Democratic Republic of Congo has affected him. 

The Enclave will be on show until June 22nd at The Photographer's Gallery, 16-18 Ramillies Street, London W1.
