The laws of central perspective state that in a picture the parallel lines of objects below the eye level converge upwards, while those of objects above the eye level converge downwards, and that those of objects to the right converge to the left, while those of objects to the left converge to the right. Artists, however, have not consistently applied these rules, but they have often used inverse perspective, in which parallel receding lines may diverge in a picture instead of converging. Non‐perspective effects may be actually observed experimentally in binocular vision, as in viewing an object the size of a matchbox at 1–2 ft. from the eyes. This and other examples are discussed, and it is shown that the strict rules of central perspective are not necessarily in accord with the facts and laws of vision. The convergence of parallel lines of objects below eye level should be increased in a picture, while that of parallel lines above the eye level should be decreased, in comparison with strict geometrical perspective.
