The third part of the implied line exercise is to take two photos, one with an implied eye line the other with lines that point.
The first image below shows the eye line between the smoker in the foreground and the one in the background. There is a second line between the cigarettes.
The secon image the lines that point are firstly the obvious of the anchor pointing out to sea then the less obvious of the discarded shoe pointing toward the anchor, the line that the wearer would walk toward the anchor. There is almost a thirsd of the rocks on the left pointing toward the anchor.
