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, makeup, and model painting, due to their ability to produce gradients and intricate designs. Airbrushes come in different types, such as single-action and double-action models. Single-action airbrushes control the paint flow with a single trigger, while double-action models allow for more precise control over both air and paint. This versatility makes airbrushes popular among artists and hobbyists alike.
