All of us
must already known what is drawing. But a good drawing includes a lot of drawing
different drawing techniques to create the illusion of 3 - D space and forms on
flat surface. Although contour drawing is quick and simple, it cannot richly
represent a 3 - D object. Artists try using shades. Shading can create 3 - D
effects because shading shows the dark and light parts of a surface. This kind
of illusion is called the illusion
tonal drawing to create the effects of light and shadows, or light and
dark tones. They use gradual change to create different shades of light and
dark. The amount of light or dark in an object or an area is called value.
light falls on form, the lit parts appear bright and the shadows appear dark.
Shading is used to show the contrast between light and dark. It helps to
describe the form.
usually draw the contours of a form first, then add shadows later. Some of the
techniques that artists use to show light and dark are hatching, wash and
stippling. These techniques show different dark values of shaded or ' filled -
in ' areas.
may be either dry or wet. Dry drawing mediums include pencils, charcoal,
coloured chalk or pastels, wax crayons and oil pastels and felt pen. Wet mediums
include pen and ink.
different mediums creates different effects. When drawing with wet mediums, the
type of paper we use is important. For example, lines will be soften when
soaking into absorbent paper. Less absorbent paper produces a clear lines.
hardness and softness of pencils are represented with ' H
' ( hard )
or ' B ' ( black ). '
H ' pencils are hard, so they draw lighter
lines. ' B 'pencils are soft, so they draw darker lines. Both '
H ' and '
pencils have different degrees of hardness or softness. These is a number (
usually 1 - 6 ) before the H
letter on a pencil. This tells you about the
degree of hardness of the pencil. A 1H
pencil is the least hard, and a
is very soft. You can clear up pencil lines with an eraser.
We can also use
watercolours to draw some other kinds of picture. And you will find that art can
be colourful !!!
