"Much tourism involves a hermeneutic circle. What is sought for in a holiday is a set of photography images, which have already been seen in tour company brochures or on TV programmes. While the tourist is away, this then moves on to a tracking down and capturing of those images for oneself. And it ends up with travellers demonstrating that they really have been there by showing their version of the images that they had seen before they set off.
Thus, effectively, people travel in order to see and photograph what they have already consumed in image form: thus, mobile reproductions are far more important than the sight itself that, in turn, is reduced to nothing but (another) picture."
