Harry Callahan (1912-1999) was one of the most influential American photographers of the second half of the twentieth century. Callahan's highly original oeuvre involved a wide-ranging exploration of photographic techniques including experimentation with exposures, a strong sense of line and form, and light and darkness. A crucial addition to Callahan's critical presence and leading to a deeper understanding of the photographer's greater impact on the techniques and styles of modern photography, Harry Callahan: The Street explores the artist's lesser-known works, focusing on his black-and-white and colour street photographs. Bringing together documentary work, still life and staged photographs-many of his wife, who he photographed throughout his life-this important review sheds new light on Callahan's personal and pioneering approach.
