Leading lines are an often used technique that guide a viewer's eye through the image to the subject or an important element of the subject. A leading line can be almost anything: perspective lines, a road, path, sidewalk, fence, river, tree line, shadows, stair rail, painted lines on an object, architectural elements, etc. Leading lines should serve the purpose to lead into, not out of, the image, and they should lead your eye toward the main subject. These lines can be very powerful, adding depth to the image.
While leading lines are often associated with landscape photography, I believe they can be a powerful composition tool used in abstracts, street photography, still life, almost any genre.
The simple requirement for this challenge is that your image contain one or more lines, explicit or implied, which serve to guide the eye into and through the image, or guide the eye into the image towards an element of the primary subject.
