Martin Schoeller is a photographer best known for his celebrity portraits. His signature portraits are extreme closeups. He calls them hyper-detailed, and they reveal every hair and pore. He’s taken pictures of celebrities such as Bill Clinton, Angelina Jolie and Robert De Niro, and his work appears in glossy magazines including Vogue, Time and The New Yorker. His latest project, however, is different. He has been photographing homeless people in Los Angeles and posting the images to Instagram.
