Remember, each of these, or several used together, can help improve your photos. Still, it requires an experienced eye to put these ideas to their best effect. Don't get discouraged if some photos you take, even those containing these concepts, still don't look quite right. LINE - Line is one of the simplest concepts to describe. Basically, it is including things with strong, defined lines in your photo.
Examples are things like the edge of buildings, train tracks, road lines, and sidewalks.
It is not limited to simply solid objects like buildings, or even to straight lines. Light and shadow, with a clear edge between them, can create Line. Many photos have curved lines, such as roads as they bend to the right or left, or a footpath that winds between the roots of large trees, as well. The most common Shape used is the circle. We can see that in tapestries, or in arched doorways.
