Silhouettes

In the area of photography, a silhouette is defined as an outline that appears dark against a light background. More specifically, it is where your subject appears as a plain black shape against a brighter background. It is an artistic photography expression that many photographers like to refine and perfect in their images. This effect can be achieved with any bright light source with the sun being the most common. In a sunset silhouette photo, the sunlight in the background is exposed correctly forcing everything else in the photo to be underexposed causing the effect.
