When lines intersect, they can pause the viewer's gaze, creating a sense of tension or conflict in the composition. These intersections can also redirect focus within the image. When lines from the foreground and background converge, they generate a sense of depth or distance. A classic example of this is the vanishing point, where a road meets the horizon.

Vertical lines naturally guide the viewer’s eye upward or downward within an image. They convey strength and confidence, which is why they are often used in fashion photography, portraiture, and street photography. In urban environments, you’ll frequently encounter vertical lines in elements like lamp posts, window frames, and other architectural details.

For a dynamic composition, consider using diagonal lines. These lines create a sense of movement and transition, though they are less frequently seen in photos. Diagonal lines are effective at emphasizing depth, drawing attention from the foreground to the background.

Horizontal leading lines are commonly used in landscape photography, such as a path, dirt road, or fallen tree leading towards a river. These lines create a feeling of stability and continuity, offering a sense of reliability and calmness in the composition.

Natural, meandering lines are prevalent in landscape photography. Curved leading lines are particularly effective because they guide the viewer's eye throughout the entire image. Whether it’s the gentle arch of flower stems or the undulating shape of rolling hills, these curves can add a captivating element to landscape compositions.
