ANN ARBOR, Mich. (AP) — A traveling exhibition opening this weekend at the University of Michigan Museum of Art looks at the use of 19th-century photographic methods by contemporary photographers.

The exhibition is titled "The Image Wrought: Historical Photographic Approaches in the Digital Age" and includes about 80 works, including cameras and equipment. It opens Saturday and runs through Jan. 17.

Officials at the museum in Ann Arbor say a growing contingent of contemporary photographers is revisiting the daguerreotype, cyanotype and tintype instead of using the latest digital photography methods.

The traveling exhibition was organized by the Harry Ransom Center at the University of Texas at Austin.
