Leading lines help the eye to enter a picture. Normally, they lead the way towards the main subject (if there is one). You can find leading lines formed by roads, rivers, fences, boardwalks, shorelines, handrails, moving stairs, walls or train tracks. These lines can also help create a connection between the foreground and the background and give some depth to the picture. You should carefully consider to use leading lines in order to help the viewer endeavour your picture and lead them to your story.
