写真の奥行き知覚における空間の異方性について

How can we reproduce real physical depth from a photograph? How does depth perception in the photograph differ from depth perception in the direct observation? In Experiment 1, objects in an open space were photographed and presented on a screen. Subjects were asked to judge the distances from a fixed point to the objects and the angles from the median line. The distances and the angles in the photograph were perceived shorter and larger than in physical space, respectively. Furthermore, depth perception in the photograph had an anisotropic property. In Experiment 2, the same objects as in Experiment 1 were observed directly by the subjects. The distances and the angles in the direct observation were perceived longer and smaller at longer distance than in the photograph, respectively. It was concluded that depth perception in the photograph did not reproduce depth either in physical space or in visual space, but it was closer to depth in visual space than in physical space. Furthermore, photographic space had an anisotropic property as visual space did.
