Chris Rainier recently released his latest book, Ancient Marks, which documents traditional tribal tattooing around the globe. Images from the book were displayed this summer on the photo screen in New York City’s Times Square. Rainier’s portfolio also was included in the October 2004 issue of National Geographic Adventure magazine.

Rainier, who specializes in documenting indigenous cultures, is a codirector of the Culture Initiative and Ethnosphere Expeditions at the National Geographic Society. From 1980 to 1985, he was a photographic assistant to the late Ansel Adams.
