Architectural photography can be described in several ways. One common sense approach identifies 3 different categories, which do overlap a bit:
Documentary -- the focus is on representing the building as accurately as possible in whole and in part, as it appears to an onlooker.
Environmental -- the focus is on the building in its natural and human context -- so images including landscaping, other buildings, the natural environment, as well as people using the facility.
Artistic -- the building is presented in a fashion to make a broader artistic statement about the building, an aspect of it, etc.
