Leading lines are visual elements within a frame that naturally draw the viewer's eye toward a specific point, subject, or direction. These lines - whether literal lines like roads, fences, or architectural features, or implied lines created by the arrangement of objects - act as visual guides that direct attention and create a sense of depth, movement, and compositional structure.

In photography and cinematography, leading lines are a fundamental compositional tool used to draw attention to the subject, create depth by converging toward a vanishing point, establish a sense of direction or movement within a static frame, and give images a dynamic quality that feels intentional and purposeful. Common leading lines include roads stretching toward the horizon, hallway corridors converging on a doorway, riverbanks curving toward a focal point, or rows of trees framing a central path. When lines converge at or near the subject, they anchor the viewer's gaze and create a sense of visual weight and importance around that element.

When prompting image or video generation, describing leading lines explicitly - "a road converging toward a lone figure in the distance," "hallway perspective lines framing the subject" - helps communicate desired compositional structure. Strong leading line compositions tend to produce visually compelling results with clear focal points and a sense of depth.
