Strange Garden:Portrait of a tree

"A silhouette is a view of an object or scene consisting of the outline and a featureless interior, with the silhouetted object usually being black. The term was initially applied in the 18th century to portraits or other pictorial representations cut from thin black card.

The term has been extended to describe the sight or image of a person, object or scene that is backlit, and appears dark against a lighter background.

Silhouette images may be created in any artistic media, but the tradition of cutting portraits from black card has continued into the 21st century."
