"...by limiting experience to a search for the photogenic, by converting experience into an image, a souvenir. Travel becomes a strategy for accumulating photographs. The very activity of taking pictures is soothing, and assuages general feelings of disorientation that are likely to be exacerbated by travel. Most tourists feel compelled to put the camera between themselves and whatever is remarkable that they encounter. Unsure of other responses, they take a picture. This gives shape to experience: stop, take a photograph, and move on. The method especially appeals to people handicapped by a ruthless work ethic--Germans, Japanese, and Americans. Using a camera appeases the anxiety which the work-driven feel about not working when they are on vacation and supposed to be having fun. They have to do something that is like a friendly imitation of work: they can take pictures."
