These eye-opening and beautiful photographs offer an insight into the lives of some of the planet's last indigenous peoples.
Photographer Jimmy Nelson has travelled the globe for decades, spending time with remote and diverse communities.
From Siberia to Tanzania, his pictures offer a rare glimpse of indigenous cultures that face the very real threat of being consigned to the history books in the 21st century.
By sharing his photographic project, entitled 'Blink and They're Gone', Mr Nelson hopes to raise awareness of the importance of preserving these cultures.

He said: "If we let the cultural identity of the indigenous people disappear now, it will be lost forever.
"It's literally a case of blink, and they're gone.
"And if this happens, we will lose one of the most valuable assets we have - our rich human cultural diversity and heritage."
Mr Nelson went to extremes to capture the striking photographs. In the Yamal Peninsula in northern Russia, he braved - 50C temperatures with the Nenets, who wear huge furs to protect themselves in the elements.

In Chad, he documented the Wodaabe men's judgement at the Gerewol festival. By contrast to Western culture, the men wear make-up and adorn dresses to impress female judges as part of a beauty pageant.

Another photograph depicts the Huli wigmen, who live in the southern highlands of Papua New Guinea. Their bold yellow face-paint contrasts starkly with the green foliage of the forest around them.

As awe-inspiring as the photographs are, Mr Nelson has previously been criticised by anthropologists for the self-professed 'aspirational and stylised way' he presents these cultures.
But Mr Nelson has defended his style, arguing that his photographs could help to send a powerful message.

He said: "Our collective cultural identity is too valuable to be destroyed by homogenisation.
"The depth and wealth of our humanity will shrink. This must not happen.
"We must unify and fight to support indigenous cultures and take personal pride in the myriad of their cultural traditions that are still to be found on the planet today."
Mr Nelson is hoping the short film constructed from his photographs will play a part in a wider movement to preserve the cultures of indigenous peoples.
