What to look at
Repeated equal objects are the clearest lesson in diminution: each row of desks is smaller and closer together than the last.
Both figures' eyes are on the horizon because they stand on the same floor as the camera; the shorter one's head sits a little lower.
The desk tops (0.75 m) are all below eye level, so every one shows its top surface.
