Getting The Airbrush Basics Down Pat
What's happening once you spray?
Let's explore the essential underlying concepts of spraying with the airbrush. Knowing what's happening and why, you'll have the capacity to bend or perhaps break the standard rules to generate stunning effects and techniques.
"Knowledge is power"
Airbrush basics get started with the spray. Knowing what's happening offers you the energy to regulate and modify the consequences you're seeking to achieve.
Technical jargon warning.
An aerosol spray is a blend of several liquids using a gas. The liquid gets broken up into tiny droplets, atomized. The atomized liquid is suspended inside the gas, usually air.
Liquids in suspension have a tendency to settle. It gradually falls for the floor.
End of technical jargon.
If the liquid hits air stream the force in the moving air breaks up and atomizes the liquid into small globules (think tiny spheres although not nearly so neat and perfect as being a sphere needs to be).
If the globule hits something it forms a dot. The height and width of the dot is determined by how much the droplet dries before impact with the surface.
Greater air pressure = smaller dot = drier, rougher spray texture
Lower air pressure = larger dot = wetter, smoother spray texture
A large number of these tiny dots (a lot of them smaller than you will notice) form larger shapes as dependant on the consumer.
Users try to spray with as little pressure as possible, but enough to actually break up the paint being sprayed.
Thicker, chunkier paint = greater pressure to pull and atomize the paint
Runnier, more uniform paint = less pressure to pull and atomize the paint
