This is a portrait of painter Agnes Martin from the book,'Annie Leibovitz At Work'. In the book, Leibovitz describes Martin as a Buddhist, who believes that art is an interaction with the divine. She asked Martin what she does every morning in the studio, to which Martin answered "I sit here and wait to be inspired." This portrait shows Martin (and Leibovitz?) perhaps at that moment of inspiration.
I love that she tries to portray an inner experience with an exterior event.
