These photographs, their backdrop the grueling misery of sharecropping during the Depression, exhibit freedom's hidden measure.The spare, minimalist portraits Dorothea Lange sets on the stark geography of fertile fields have a pull beyond their obvious irony and harsh details.Still not fully tapped by scholars is Lange’s Library of Congress FSA archive, including 1,179 negatives from the American South. This collection curates several studies of her photographs, explores her craft and technique, and a new catalog of her art, as she photographed the American South between 1933 and 1938. Print publication will soon follow.
