Discover the Pattern of Light and Shadow chapter 5
Observe the object at its edge. As the form turns toward the edge of the
object in the light area, notice that the tone of that area begins to get
slightly darker. This is difficult to distinguish, as it is often a very subtle
change of tone. The addition of these shapes of slightly darker tones will
help the form turn, which adds volume to the object you are drawing.
These darker shapes of tones within the light area are referred to as the
light half tones. Remember that the light half tones cannot be as dark, or
even get close to being as dark, as any tone within the shadow.
Note:To erase small areas, shape your kneaded eraser into a point.
The artist continued to develop the drawing, observing all areas in rela-
tionship to each other. Notice how the light on the wall begins to show a
gradation of tone that indicates the direction of the light. The shape of the
light on the table further enhances the direction and quality of the light,
by defining the shape of the shadows of the objects sitting on it. (See the
final stage of the drawing on page 65).
TIP
Keep your kneaded eraser clean by continually
kneading it! If you don’t keep turning the eraser in
on itself, it will not be able to erase more graphite,
as the surface will already be overloaded with too
much graphite. Keep finding a new surface to use.
