Airbrush uses are seriously limitless. From decorating a car to a
motorcycle to an old t-shirt, one can give new life to anything he or
she chooses. The great thing about airbrushing is that each piece of
artwork is unique. For
those who don't know an airbrush works by passing a stream of fast
moving (compressed) air through a venturi, which creates a local
reduction in air pressure (suction) that allows paint to be pulled up
from an interconnected reservoir at normal atmospheric pressure. The
high velocity of the air atomizes the paint into very tiny droplets as
it blows past a very fine paint-metering component. The paint is carried
onto paper or other surface. Airbrush operator controls the amount of
paint using a variable trigger which opens more or less a very fine
tapered needle that is the control element of the paint-metering
component. An extremely fine degree of atomization is what allows an
artist to create such smooth blending effects using the airbrush.
The airbrush technique allows for the blending of two or more colors in a seamless way, with one color slowly becoming another color. Freehand airbrushed images, without the aid of stencils or friskets, have a floating quality, with softly defined edges between colors, and between foreground and background colors. A well skilled airbrush artist can produce paintings of photographic realism or can simulate almost any painting medium. Painting at this skill level involves supplementary tools, such as masks and friskets, and very careful planning.
