An airbrush is a small, air-operated tool that sprays paint or other liquids through a nozzle. It uses compressed air to create a fine mist, allowing for smooth and detailed application of color. Airbrushes are commonly used in various fields, including art, cosmetics, and automotive painting, due to their ability to produce gradients and intricate designs. Airbrushes come in different types, such as single-action and double-action models. The single-action airbrush controls the paint flow with a single trigger, while the double-action airbrush allows for more control over both air and paint flow. This versatility makes airbrushes popular among artists and professionals alike.
