Cezanne said that in life there were 4 major forms; the rectangle, the sphere, the cylinder and the cone. This viewpoint is helpful when drawing and painting light and shadow. The human head can be viewed as an elongated sphere or 2 overlapping spheres. Arms, legs and tree branches can appear to be cylindrical in form. I have often looked at mountains and seen rectangles or wedges of rectangles. Some hats and other objects might be viewed as cones. These forms can be upside down, foreshortened or in part. A half of an orange might be seen as a half sphere. When you look at light and shadow, changes of value are more subtle in spheres, cylinders and cones. A rectangle or wedge has stronger contrasts at their edges. See a wedge shape on top of a tower. The contrast between the light, local colour and shadow is sharp. Artists can alter this light on forms. I saw a wonderful painting where the artist used more distinct contrasts of light and shadow when painting people and horses. This sharp value contrast made the painting dynamic.
