Martine Fougeron, Adrien and Nicolas Dining, 2005. All images courtesy the artist

Martine Fougeron began photographing her then-teenaged sons 15 years ago, but it became a long-term project, and now a book, Nicolas & Adrien (Steidl), that captures the nuances of their changing relationships with each other as well as friends and girlfriends. See our March/April issue for a portfolio of those photographs.
