Mercadier lives in Paris and is represented by Galerie Les filles du calvaire, Paris. With an interest in dance, architecture and interstellar spaces, she carries out her stagings, previously drawn in sketchbooks, by using models, dancers and actors. Mercadier makes the costumes and the sculptures launched during the shots. Until 2008, she worked with a Polaroid SX70 camera, before she turned to digital.
