EXERCISE
8: TONES AND VALUES
The values are the different tones which go
from dark to light. In a black and white drawing, you can express these
with intense greys which vary from dark to light.
Furthermore, the values produced by the
light, their effect and the shadows that are projected, there is
another type of value that we call local value, these are produced by
the actual colour of the object.
The complete range of tones is called the
"guideline of values" and is a combination of:
the local values: in the example that we
have drawn, the fur of a white spotted dog.
the values that the light produces when
illuminating our object and the dark shadows that it projects: in the
example below, you can see the shaded dog with a spot light which comes
from the top right.
In the last drawing, you can see the result
of combining local values and light/shadow, that is to say the
guideline of values.
