Architecture
Drawing buildings can be a lot of fun. Basic building form is
somewhat rectangular in shape and it modulates light and shadow
more vividly than landscape does. Because of the angular rela-
tionship between the planes, the tonal contrast between them
is sharp and strong. Vertical planes include all the walls, columns,
windows, gateways, doors, etc. Horizontal planes include ceilings,
floors, terraces, tabletops, flat roofs, and minor horizontal sur-
faces. A pitched roof is an inclined plane, and the inside of an
archway is a slightly curved plane. These planes come together
to create spaces. Depending on the direction of the sun, one or
more planes may be in sunlight while the opposite sides of the
same planes are in shade. Similar planes also cast shadows, and
the tonal values of the shadows are generally darker than those
of the shaded planes. A good sketch is the result of looking for
ways to develop a meaningful pattern and manipulating the vari-
ous tonal values. For example, the details and pattern of the
masonry of a very interesting house may have to be sacrificed
if the plane happens to be in direct sunlight, as it is sometimes
more important to establish a strong tonal contrast than to
show the details.
