Photographs from Vietnam to Afghanistan to Iraq capture the agony of war in an instant. This hour, we’ll talk about how war photographers tell stories of conflict through their images with a panel of Pulitzer Prize-winners: David Hume Kennerly, Carol Guzy and David Leeson. Tonight, they’ll take part in “Illusion and Disillusion: A Panel Conversation on Violence and War” at the Texas Theatre, presented by 29 Pieces.
