In her essay, "Against Interpretation," Susan Sontag argues that merely identifying the symbolic features of literature or art is a form of translation that can limit our ability to appreciate the genuine creativity of artistic works. Sontag's work on photography was important in fertilizing educators' ideas about representation and reality. Her essays on photography explores how the convenience of modern photography has created an overabundance of visual material, since "just about everything has been photographed." This has altered our expectations of what we have the right to view, want to view or should view. "In teaching us a new visual code, photographs alter and enlarge our notion of what is worth looking at and what we have the right to observe" and has changed our "viewing ethics." Photographs have increased our access to knowledge and experiences of history and faraway places, but the images may replace direct experience and limit reality. Photography may desensitize its audience to horrific human experiences, and children are exposed to experiences before they are ready for them. The problem of our reliance on images and especially photographic images is not that "people remember through photographs but that they remember only the photographs ... that the photographic image eclipses other forms of understanding—and remembering. ... To remember is, more and more, not to recall a story but to be able to call up a picture" (Sontag, 2002, p. 94).
