Annie Leibovitz is arguably America’s most famous portrait photographer. Her shots of actors and musicians have made the covers of Rolling Stone, Vanity Fair and many other magazines. She joins us to talk about the work that goes into her extraordinary pictures, many of which are captured in her new book, “Annie Leibovitz: Portraits 2005-2016” (Phaidon Press). She speaks tomorrow night at McFarlin Auditorium as part of DMA Arts & Letters Live.
