Lines are one of the simplest and most powerful elements in art, photography, and everyday life. They can be straight, curved, diagonal, horizontal, or vertical, and each type can create a different feeling. Lines can guide our eyes toward a subject, create depth and movement. In photography, roads, railway tracks, bridges, fences, rivers, and buildings can all create natural lines that lead the viewer through a photograph. Lines can be seen everywhere around us learning to notice them can help us see the world in a more creative and beautiful way.
