One of the most effective ways to create a powerful composition is to use visual elements to lead the viewer’s eye into the scene. Leading elements can be just about anything—lines, curves, or a progression of shapes. Leading lines that stretch from foreground to background are especially powerful, propelling the viewer into the scene. In the image at left, I used an outgoing wave to act as a leading line. Other shapes placed in the foreground can do the same: a curving river can compel the eye to meander throughout the frame, whereas a triangle-shaped rock can point into the composition. Multiple elements can more subtly encourage the viewer to explore the photograph—a near-to-far, bottom-to-top visual progression is often particularly effective.
