There are various forms of lines and which you use will determine the end result of your photograph. If your line begins at the center or edge of your photo it can split the photo in half, your photograph will have a more impressive outcome and stronger composition if your leading line begins at the corner of your photograph.
Making use of lines in photography is a photographic composition technique used by many professional photographers, and for good reason. Lines - also referred as “Leading Lines” - can be used to lead the eye to the point of interest and prevent the eye from wandering. Lines can put emphasis on distance or illustrate a relationship to foreground and background elements. Keep in mind that using lines incorrectly can have the opposite effect and lead the eye away from the point of interest.
