The film has no narration. Instead, the story of the moor's history, archaeology and people is told by contributors, poets and musicians.
Folk singer Seth Lakeman, who lives in Yelverton, is featured in the film, as is poet Alice Oswald, while Postbridge musician Nigel Shaw has composed the score.
Chris was born in Wigan, Lancashire, but moved to Dartmoor in 1975. Since then, his photographs have documented life within the moor.
He says the scale of this latest film developed and grew: "We started filming in July 2007 with the idea of covering the seasons.
"However, film-making is an organic process and as we archived the material a new shape to the film emerged.
"We didn't want a presenter or a documentary style, so we chose to film the people and then let them tell their story.
"We then approached the poet Alice Oswald, whose wonderful poem 'Dart' describes so beautifully the heart of the moor and the talented musician, Seth Lakeman who, through his brilliant songwriting, gave us an insight into Dartmoor's myths and legends.
"He plays his fiddle in the film and sings Kitty Jay.
"Whilst working on his recently released Dartmoor Symphony, recorded with the Ten Tors Orchestra, Nigel Shaw, who's also a Dartmoor resident, collaborated with us to provide a sound track that complements the visual imagery.
"Little by little the story of the moor started to emerge. We hope the result will give the viewer as much pleasure as we had in making it."
