Shadows on two planes—horizontal and vertical—oblique planes. Shadows cast on curved surfaces. Shadows by a curved surface on two planes—on curved surfaces. Shadow cast by a sphere.
Artificial Light.—Interiors, one light—two or more lights on planes at any angle.
Reflections.—Angle of incidence and reflection. Point of incidence. Horizontal reflecting planes—still water. Vertical reflecting planes—perpendicular, parallel, or at an angle with the picture, lnclined reflecting planes at any angle with the picture.
