"Some complain that architectural photographs are too often fakes - that they are too often contrived and do not reveal the true aspect and character of a building"
-Eric de Mare
(Photography and Architecture, 1961)
The camera can obscure and ignore areas that would disrupt the desired view and therefore present a false representation.
Joining images together using the elements of the building allows us to become more aware of the building's features as a whole, and places together the missing components, which would often be left out for the benefit of aesthetics.
