french photographer eric valli has spent over twenty years documetning the peoples of the himalayas, including the dolpo, seen here, who live between tibet and nepal in one of the highest inhabitable regions in the world.

"they work hard, but want for nothing," he says. "they are happy and alive."

eschewing digital cameras, valli continues to shoot with his leicas. “i might take an okay picture, but what i’m looking for is an enthnogrpahic testimony of the human adventure; a complete existence in one picture,” he says.

“you can never just observe. because my work is all about interaction. …i have lived years and years with these people. i have nothing to teach them and they have everything to teach me.”
