Artists who embraced photography’s singular capacity to unsettle the viewer did so with a broad range of photographic techniques. Peter Hujar, Robert Mapplethorpe, Andres Serrano, Lorna Simpson, and Carrie Mae Weems based their work in—and often subverted—the tradition of studio portraiture. Hujar, Nan Goldin, and Zoe Leonard shot seemingly candid pictures, often of subjects found on the street. Kruger and David Wojnarowicz created montages with appropriated imagery lifted from advertising and other pop-culture sources. Kruger, Simpson and Weems put words in their pictures, deploying language to give political meaning to otherwise neutral images. Wojnarowicz used text in yet another way in his Sex Series, overlaying a complicated mix of images with news stories, government reports, and diary entries about homosexuality and AIDS. The exhibition was prompted by the recent removal of a 1987 David Wojnarowicz film from an exhibition at the National Portrait Gallery, in Washington, D.C., the latest of a series of controversies involving the public display of “unsettling” photographic works. In December 2010, members of Congress, spurred by conservative activists, objected to the film's imagery of ants crawling over a crucifix, and museum officials quickly decided to take the film off view. That action and the resulting public outcry were reminiscent of the culture wars of the 1980s, when politicians and religious leaders frequently denounced art they found offensive, and called for the elimination of public arts funding. As its title, Unsettled, suggests, some of the images in this exhibition are “unsettling” and may elicit strong reactions in viewers. With this in mind, parents may want to preview the exhibition before deciding whether to introduce it to their children.
