What is the difference between single and dual action brushes?
When choosing an airbrush, it is necessary to keep in mind the difference between single and dual action brushes.
Dual-action brushes allow the user to determine exactly how much they want to release at any one time. This means that you can pull the trigger just a little bit in order to spray slowly and pulling the trigger harder will mean that more paint is released. Single action airbrushes simply have a button which is pressed. In order to alter the amount of paint sprayed with single action brushes you have to move the brush closer or further away from the subject.
Generally dual action brushes are preferable because single action ones can become a bit messy sometimes. Having said this, some artists swear by single action brushes and will only use them. Single action brushes also require less maintenance.
