What Remains is a 2003 photography book by Sally Mann. The book is published by Bullfinch Press and contains 132 images on the subject of death, including photographs of decomposing bodies. The book lent its name to the 2005 film about Sally Mann, What Remains: The Life and Work of Sally Mann, in which Mann can be seen at the University of Tennessee's anthropological facility, taking photos for the book of corpses which had specifically been left outside for scientific study of human decomposition. Mann opened her exhibition for the book at the Corcoran College of Art and Design in 2004. The exhibition was divided into five sections that "visually depict[ed] the eternal cycle of life, death, and regeneration."
