The Crossing
Leading lines are an important element in guiding the viewer through a composition. Sometimes they are subtle and other times they hit you over the head and say this is how I want you to see this subject. They are also useful to tie elements of a layout together.
With the bold white line cutting across the tarmac to the feet of the walker I don’t think you could call this leading line subtle. It is bold and in your face. Without it there would be no composition. I like the early morning light and the way the photo-artist had limited our field of view so we have to use our imagination about the pedestrian in the shot.
Notice that the horizon, in this case the sidewalk edge, is nice and striate. This line is located at the feet of the subject thou we can see they have not reached the curb. With the horizon one fourth of the way down from the top of the frame the viewer has a feeling of being insignificant, almost a hidden voyeur.
My only complaint is that I wish the person in the composition were more interesting. This would give our imagination more to work with when creating a story about the subject.

Went on a recent “Photo Walk” and photographed a friend crossing the street. Photo required some work to tone down the pavement. Thanks for the review.
