EXERCISE FOUR/VARYING SHADES
This lesson is similar to the previous one.
This time you will start at the top and gradu-
ally fade into white (fig. 12). Do not fade
abruptly and do not carry the tone further
than 2/3 or 3/4 of the page. Remember, you
must stop your tone shorter each time, since
the overspray will build up. Fig. 13 is a com-
bination of masking and varying shades. The
important thing in this exercise is to train
your eye so that all the small squares have
the same tone value.

TECHNIQUES TO USE
Masking or frisket is used mostly when more
than one color is applied. A new frisket is
cut for each color and covers any area that
should not be sprayed. Badger’s
Foto/Frisket™ Film is specially formulated
for use on all surfaces commonly used for
airbrushing.
For contour masking (models, ceramics,
etc.) use masking tape, scotch tape or
Foto/Frisket™ Film and cut to desired
shape. Make sure the edges are pressed
firmly against surface to prevent underspray.
STENCILS
Stencils are used when a design needs to be
duplicated, as in posters and decorating.
Cut from stiff paper, FOTO/FRISKET™ FILM
or NO-TACK Stencil Film, hold the stencil
firmly in position and spray starting with the
edges and work inward. A reverse stencil
can also be used, spray along the stencil
edge.
A flat surface mask can be cut from
Foto/Frisket™ Film. For a sharp edge, hold
the mask flat in position. For a softer edge,
elevate the mask slightly by resting on a
ruler or other flat object.
