While reading the silhouette article I read that the most important rule in exposing for a silhouette is to always expose for the background and not the subject. It is better to underexpose one-half to one full stop to take more than one shot and to bracket exposures. I also found out that Silhouetting can take a simple photo of something seem more dramatic by making the subject look lonely or making the subject look more peaceful while reading the article. In the article it said that Manual mode is the best mode for automatic cameras. It is the best because the camera would try to adjust the background and make it look normal.
