Any effect the airbrush produces may be used for special effects in the right
situation. Selectively create special effects and use them to enhance your
Special effects are effects created to enhance illustrations by emphasizing
texture, color, or shapes. You may create special effects by varying air
pressure, raising or moving masks, increasing or decreasing the distance
between the airbrush and paper, and changing the angle of airbrush to paper
Reducing the air pressure from the air source to the airbrush will make the
pigment heavier to transport in the air.
This results in a granulated or stipple
Figure 6-26 is an example of granulation resulting from reduced air pressure.

Increasing air pressure from the air source to the airbrush provides more air
than the pigment needs to reach its destination.
The result is a random
spatter with a fine mist of over spray.
Figure 6-27 is an example of splatter.
