Fifty years ago, the world of art virtually excluded photographs from its purview. Today, it is impossible to imagine contemporary art without the presence of photography and other lens-based media. What were the causes of this profound shift, and how did it happen? This seminar will examine the art, artists, and critical discourses that together form the environment for today's photo-based art. Class sessions will include slide presentations, discussions of assigned readings, and critiques of participants' artworks and critical writings. Among the artists to be discussed are Andy Warhol, Ed Ruscha, Robert Heinecken, Bernd and Hilla Becher, Robert Smithson, Jan Groover, William Wegman, Cindy Sherman, Nan Goldin, Robert Mapplethorpe, and Adam Fuss. Readings will include essays by Michael Fried, Roland Barthes, Rosalind Krauss, John Szarkowski, and Jean Baudrillard. Students from all disciplines and art media are welcome to register; prior knowledge of 20th-century art and photography is useful.
