Scarborough Lighthouse - wide-angle image.
17mm.
The perspective is distorted by the wide view, and the pointing upward of the camera to enable the whole building to be included. There is a much better percepyion of depth, although the building appears unrealistically long, and the verticals un-naturally tilted. The backgound seems much further away than on the telephoto shot.


Scarborough Lighthouse - telephoto image.
210mm.

The perspective is compressed, with little indication of the length of the main building. There is no significant distortion of the verticals. The overall impression is of a relatively "normal" view, as we interpret the visual cues of a square, or oblong building with perpedicular walls, which this view gives.
