Flat
Shading occurs in lower right, fading as it moves to the upper left or toward the light source. Shading goes from edge to adjacent edge, perpendicular to the light source. On a flat surface, shading is straight across at a diagonal angle. Shading should fade to light or dark by about the halfway point. Regardless of the outline shape, the treatment of a flat surface is the same. Just moving from corner to opposite corner darkening or lightening as you go.

Cylindrical
You can think of something as big as a silo or small as a can of soup for this surface shape. In this case, shading occurs along both sides and gradually fades to light in the center. Take care not to make the highlight in the very center, but off to one side or the other slightly. This will make it look a little more natural. We use this cylindrical treatment when we paint pots, cans or bottles of any kind. * The shading on the top of this example is treated like a cone as if it was a silo. If the top of your cylinder is flat (like a coke can) then the top would be treated like the Flat surface shape above. |
