The National Gallery of Art explores how the practice of making multiple portraits of the same subjects produced some of the most revealing and provocative photographs of our time in The Serial Portrait: Photography and Identity in the Last One Hundred Years, on view in the West Building's Ground Floor photography galleries from September 30 through December 31, 2012. Arranged both chronologically and thematically, the exhibition features 153 works by 20 artists who photographed the same subjects—friends, family, and themselves—numerous times over days, months, or years to create compelling portrait studies that investigate the many facets of personal and social identity.
