In my opinion an Architecture Photography is somewhat a symbiosis of an architect and a photographer. In a good way they both parasitize on each other.

The architect builds a piece of art which no one can see except those who see it with their own eyes. if no one reproduce this piece of work into smaller, transmittable image and reveal all its beauties, then it will remain undiscovered. The photographer can't photograph anything without the architect's work and most likely will become a Landscape photographer.

I believe magazines and books with photographs of an architecture belong to the most beautiful ones.
