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.

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.

~ Susan Sontag, On Photography
