The silhouette is one of my favorite photographic techniques. Simply by placing a strong light source in the background, a photographer can make the subject into an outline, a shadow, something more abstract than specific -- nearly an illustration. These images always catch my eye when I'm searching through photos to use in essays, and I've collected some of my recent favorites below, from locations all over the world http://www.theatlantic.com/infocus/2012/07/in-silhouette/100335/
