Lines
are the basic components of every drawing. There are thin lines,
thick lines, straight lines, curved lines, lines that start
fat but get skinny at the end, lines that are so short that
they can be called dots....The permutations are endless (Fig
2a). In drawing the human figure, it is particularly important
to have a good control over curved lines, as bodies are rather
conspicuously short of ruler-straight edges. Consider the ink
drawing to the right. It is composed entirely of curved lines,
with no traditional solid blocks of "shading" to give
it depth. The darker "black" areas were created either
by cross hatching lines or by laying down lines so close to
each other that the human eye views them as a solid mass.
From
Fig 2b shows variation in line thickness, which though a simple
thing, can give a drawing a rudimentary sense of depth as well
as creating a more interesting overall composition. Fig 2c demonstrates
the use of crosshatching to create large areas of solid color.
By reducing or increasing the density of crosshatching, an artist
can vary the value of an area from nearly white to solid black.
The parallel lines of the hair in Fig 2d shows yet another way
in which lines can be used. Note especially how the open lines
near the crown of the hair become denser as they curve down
and left, creating the look of hair highlighted by a strong
light source.

Once
you've mastered the fine points of line, it's time to look at
shading.
In
the picture to the left, you may notice a higher degree of realism
than in the example image from the previous section on line. This
is due to the use of shading, which, when properly done, will
trick the eye into believing that a two-dimensional image actually
exists in three-dimensional space.
(Fig
2f) This detail of the man's head permits us to see that a combination
of lines and shading were used to render his face and hair. The
major lines and features of the face and hair were first sketched
in lightly, then the pencil was used to put in the values of the
major planes--forehead, jawline, cheek bones, the side of the
nose, etc. Several guiding strands of hair were also drawn initially
and then blocked in with dark shading while allowing enough lighter
areas of the locks to show through to keep the mass sufficiently
"hair-like".
(Fig
2g) The torso of the figure is primarily modelled with only tonal
shading. There are few actual lines involved in this area. Instead,
the musculature of the chest is rendered by seamless shading that
attempts to duplicate the smoothness of human skin.
(Fig
2h) Directional shading in this detail shows how shading can be
used to simulate the texture of fabric.
