CHICAGO.- The Art Institute of Chicago presents today Harry Callahan: The Photographer at Work, on view through September 24, 2006. The most important American photographers of the 20th century, Harry Callahan holds particular significance for Chicago, where he made some of his most influential work. This exhibition will present Callahan's key images, focusing on his intuitive and experimental methods.
