In the photo above, the aspects of depth are more dramatic for sake of the photo. However, this is just a hyperbolic example of another cue of perception. The lines of the brick seem to lead in to a single point. In perceiving this street without the camera, we would perceive the buildings leading in to show that this pathway is long and straight. In addition, the people at the top of the image would be perceived to be farther away because they are smaller. Again the buildings farther away are blocked from the buildings that are closer, telling us that the blocked buildings are farther away.
