The visual elements of an image include dot, line, plane (or shape), texture, and color. A dot is the smallest element and has no dimensions. Dots of different sizes and colors can create sensations of depth and volume. A line is a moving dot that has position and direction. Lines of different weights, directions, and variations in direction have psychological impacts. Plane or shape refers to two-dimensional surfaces like spots or brush strokes that have height and width but not depth. Organic and geometric shapes are two types of planes. Texture is the visual or tactile quality of surfaces due to their material. Tactile texture is the actual 3D feel while visual texture is the 2D illusion of a surface's texture.
