“As photographs give people an imaginary possession of a past that is unreal, they also help people to take possession of space in which they are insecure. Thus, photography develops in tandem with one of the most characteristic of modern activities: tourism. For the first time in history, large numbers of people regularly travel out of their habitual environments for short periods of time. It seems positively unnatural to travel for pleasure without taking a camera along. Photographs will offer indisputable evidence that the trip was made, that the program was carried out, that fun was had. Photographs document sequences of consumption carried on outside the view of family, friends, neighbors. But dependence on the camera, as the device that makes real what one is experiencing, doesn’t fade when people travel more. Taking photographs fills the same need for the cosmopolitans accumulating photograph-trophies of their boat trip up the Albert Nile or their fourteen days in China as it does for lower-middle-class vacationers taking snapshots of the Eiffel Tower or Niagara Falls.

A way of certifying experience, taking photographs is also a way of refusing it—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 something to do that is like a friendly imitation of work: they can take pictures.”
