Stand at the end of your street and look down it. Or even try this
experiment by standing on train tracks, just make sure no trains are coming.
What do you notice? The street (or tracks) looks narrower in the distance compared to where you are standing. This effect is known as converging lines, and is especially noticeable in photographs.
In photos, converging lines act like an arrow, leading the eye to the subject. Another great way to add emphasis to your pictures.
