Réhahn is a French photographer based in Hoi An, Vietnam. Known as the photographer that "captures souls", he is recognized for his portraits of Vietnam, Cuba, Malaysia and India, and for his cultural preservation work.
In 2011, he launched The Precious Heritage Project with the goal of increasing recognition of Vietnam's diverse tribes through stories examples of their craftsmanship, and large scale portraits of each group in their traditional clothing. The project explores the histories as well as the changing futures of the tribes as globalization and development alter their homelands and subsequently their traditions.
On January 1, 2017, Réhahn opened the Precious Heritage Art Gallery Museum with the goal of creating a single place to preserve the artifacts and costumes he'd been given by the chiefs of many tribes as well as to share the portraits, stories and musical traditions of the ethnic groups. The museum is free to the public.
Réhahn completed his primary mission of meeting all 54 officially recognized ethnic groups in September 2019 and continues his research to discover the numerous subgroups that are spread throughout the country.
