Your photograph this month does not have to be “about” lines – but it should demonstrate a close attention to how lines build a composition. In particular, see if you can incorporate some “leading lines” – though it’s not required. Leading lines are simply lines in your photograph that draw the viewer’s eye to the photo’s subject. They usually “come in” from outside the frame; often from a corner, but not necessarily.
Feel free to construct a scene, or simply wander about looking for naturally occurring lines. Once you start keeping an eye out for them, you’ll begin to notice them everywhere!
