He shows things from the side of the oppressed, the unseen – those living in substandard housing (1994), those without papers (1995), the Mapuche Indians in Chile (Revolts, 2003), Iraqi victims (Broken Faces, 2010), alcoholics (2011) – and tries to shine a light on their condition. As someone drawn to the peripheries, he has photographed behind the scenes of the 2002 presidential election, the making of pornographic films (Hard-bodies, 2003) and fashion shows (Behind the Scenes, 2002 and 2008). In 2012, he taught photography at Paris 1 University, and he regularly gives practical workshops at the Rencontres Photographiques Festival in Arles.
