Have you ever taken a picture when the flash didn’t fire or you drastically underexposed the picture? Has your auto-focus / metering camera ever misread a scene and the subject came out almost black while the background was nearly perfectly exposed? Congratulations, you unknowingly photographed what is known as a silhouette. Technically speaking, a silhouette is a dark shape or figure seen against a light background. On occasion they can result from photographic “errors” and “accidents”, but when done on purpose, they can have a startlingly dramatic effect.
