Notes on a model of how angular width, linear width, and distance escalate. A styrofoam ball on a table is photographed at eye level making it appear much larger than its actual size. Two styrofoam balls on a table are photographed at eye level making them appear much larger than their actual size. The angular size of two balls are measured.
