I feel this is a good topic to follow simplicity. Most leading line photos are fairly simple. The main point of focus is to let the dominant line lead your eye through your photo to a certain end point. That leading line can also take you entirely through your photo and beyond. Oftentimes the viewer will want to know where that line will lead, but they will have to rely on their imagination because it’s not in the frame. That’s when you know you have an exceptional photograph, when you leave them wanting to know more.
Most of the time leading lines will be something simple, like a road or shoreline, a single point of interest.
This photo is one of our country roads, it came to mind when I was reading the Essay.
