Silhouette photography is a wonderful way to convey drama, mystery, emotion and mood in a picture. A silhouette is defined as a view of an object or a scene consisting of the outline and a featureless interior, with the silhouetted object usually being black. Pictures like these often don’t convey a clear story, and leave part of the image up to the imagination of the viewer.
The key to taking a silhouette picture would be to: choose a strong subject with a defined and recognizable shape; turn off your flash to have as little light on the front of your subject as possible; get the light right by having more light shining from the background than the foreground; frame your image so that the brightest light source is behind your subject; and make sure the silhouette shapes are distinct and uncluttered by making subjects recognizable and keeping multiple subjects separate.
