Photography is defined as the art of exposing film or a computer chip to light in order to generate an image. With the invention of digital cameras, scanners, and the like, photo manipulation and development has moved from the dark room to the home office. Along with the drawing and painting tools already discussed, when Adobe Photoshop is used in combination with a computer scanner or digital camera, it is also capable of executing dark room functions. Negatives, slides, and photographs can be imported into the computer to be edited and enhanced. As in the darkroom, Photoshop offers adjustment tools and layers to enable dodging and burning as well as techniques to saturate, de-saturate, or otherwise alter colors. The benefit of these functions over traditional photo development is the ability to maintain the integrity of the original image. The artist is free to test out infinite effects, knowing that one can always return to an earlier image state or the original photograph with the undo function and/or history palette.
Beyond photo developing, Photoshop is capable of creating seamless photomontages, or single images made up of several photographs. These images are often so well put together that it is difficult to tell that the photograph was ever altered. Creatively, this allows the artist to explore wishes and other scenarios not possible within the physical constrictions of their daily lives.
