Most months, you can see photographer Annie Leibovitz’s portraits of influential women on the covers of magazines like Vanity Fair and Vogue. Everyone from Hillary Clinton to Serena Williams to a mostly nude Amy Schumer have been in front of her lens. Her current exhibition “Women” updates a book of portraits she made with Susan Sontag back in 1999. The images now on display at San Francisco's Crissy Field reflect the changing roles women occupy today. Leibovitz sat down with KALW's Lauren Schiller to talk more about her work and process.
