Explore an overview of Chicago-based photographer Dawoud Bey’s portraits of contemporary society since his 1979 breakthrough with the “Harlem U.S.A.” exhibit. Although Bey has continued to focus on African-American subjects during his long career, his work is marked by a mixing of protocols. He uses both small and large-format cameras, as well as Polaroids. His photos include black-and-white and color, studio work and on-the-street candids. His wide array of works is featured in museums across the United States. The “Picturing People” exhibit of 50 images opens June 7 and runs through Sept. 9. In honor of the exhibit’s opening, Bey will discuss his work at a special Art Talk at 7 p.m. June 7.
