Of photographic subjects: positioned between a light source and the camera (i.e., positioned so that the light is coming from behind the subject). Pleasing results can be achieved by silhouetting the subject in a halo of light (rim light). It also provides separation between the subject and the background and can create a transparent effect with some subjects.
