Brush strokes refer to the marks made by a paintbrush on a surface, such as canvas or paper. These strokes can vary in size, shape, and texture, depending on the type of brush used and the technique applied by the artist. Different brush strokes can create various effects, from smooth and blended areas to rough and textured ones. In painting, artists often use specific brush strokes to convey emotion or movement within their work. Techniques like impasto, where paint is applied thickly, create a three-dimensional effect, while wash techniques produce soft, translucent layers. Understanding brush strokes is essential for both creating and appreciating art.
