CHANGING FACES

Various tribes, Vietnam

Visitors exploring Vietnam will soon encounter the huge variety of cultures, cuisines and coutures of the country's tribal groups – there are 54 officially recognised by the government. Since he moved to Vietnam seven years ago, French photographer Réhahn has been on a mission to document them; he's up to number 49. “I'm waiting for permission because some tribes are in sensitive areas,” he says. “It can take up to three years to get permission.” The challenge is already reaping rewards: proceeds from the sale of Réhahn's prints and books support a range of social enterprises in Vietnam, including a museum about the Co Tu ethnic group.
