Learning Goals:

Train your eye to recognize a full range of valuesDevelop the ability to render a full range of values, using various media

Use value to model form

Use value to distinguish shape (detail)

Value refers to tones.

-darks.....lights......and middle tones

Tones are created when light and shadow interact with objects.


5/63

Value can be used to distinguish one shape

from another, instead of line (outlines).

No outlines-just tonal

Value is used to model form and

make objects look 3-dimensional.

Changes in value

especially help to

model form. When

values change fromdark to light, we call

these gradations.

Light Tones

Different forms of mark making can be used

to lay down tones.

-in this case, line is being used to create tones.

Sometimes mark making = texture!

Artists try to use a wide range of tones.

Producing a Wide Range of Tones

To produce a wide range of tones, do one or more of the following:

(depending on the medium)

-press harder / press lighter

-use (lay down) more or less of the medium....tocover more or less of the paper (surface)

-use a darker-toned tool (such as softer graphite)

Harder Graphite(lighter mark)

Softer Graphite(darker mark)

Goal:

Learn to use a variety of pencils (varying in graphite hardness) anda variety of pressure (by hard how hard one presses) and a varietyof mark making (by laying down more or less graphite in a given area)in order to........

...........produce a wide range of tones.

No two

shapes

should

have the

Add variety by creating

Add variety with

Now use

an eraser to make

two adjacent

shapes have almost

the same tone,

then use some

line (with varied

width and/or weight

to distinguish

contour.

Your task is to vary pencil pressure and switch pencils,in order to create a spectrum of tones(values) that range

from very dark (on the far left) to very light (almost the

white of the paper.....on the far right).

Value refers to tones.

-darks.....lights......and middle tones

Tones are created when light and shadow interact with objects.

Here's a spectrum showing a wide range of tones:

Tonal Gradations

A gradation is a slow and gradual change

in a tone. Artists create tonal gradations to make

shapes appear more three dimensional.

Create gradations by:

When artists create tonal gradations, in blackand white or colour, shapes begin to look more

three-dimensional.

Using gradations, shadethe rectangle darkest atthe two vertical edgesand lightest down thecentre.

When a tone

is consistant, a

shape looks flat

When a shape

has tonal changes

(gradations), it looks

more three dimensional


57/63

Tonal gradations suggest light and shadowand create three-dimensionality.
