Combining Forms, Continued
Shading
Add shading to drawings after all objects are reduced to basic forms. The
most natural light comes from above and to one side of an object.
Light
from one source is easier to draw than light from multiple sources. Make
sure shading results from the same source or sources of illumination for all
objects in the drawing.
Details
Add details to drawings only after completing the shading. Details in the
foreground of illustrations appear clearly. To add realism to the illustration,
blur details as they recede into the background.
Figure 3-21 shows shading and details added to the basic form of the cannon.
