On a cloudy day, the Cathedral of Learning at the University of Pittsburgh has a softness to its stone exterior. (Its interior, as I’ve shown in the past, is equally stunning.) The sense of scale to the image (and the distortion of the wide-angle lens) can play tricks on your mind, making the whole scene seem smaller than it really is. To get a feel for the imposing/soft contradiction, concentrate on those improbably small revolving doors. They must be human-sized, right?
