Generally, when shooting architectural subjects, it is best to avoid distortion of vertical lines. But sometimes doing just the opposite can create a more dynamic image. It can give the impression of great height and creates a more powerful composition.
On a recent trip to the desert Southwest I visited the Mission San Xavier del Bac in Tucson, AZ. Built in the late 1700's, it is considered to be one of the finest examples of Spanish Colonial architecture in the United States. In its day it was a huge building, but by today's standards, while still imposing, it is not overpoweringly large.
But because of its history and its beauty, I wanted to make it look towering which was easy to do with a wide angle lens. Wide angle lenses, because of their optics, generally distort horizontal and/or vertical lines due to the extreme curvature of the lens. If you do not want distortion, keep the camera parallel to the building and do not point the camera upwards. But to increase distortion, stand close to the building and DO point the camera upwards. You will immediately see the effect in the viewfinder.
For this type of image, your point of view can make or break the shot.
