In lighting design, backlight is the process of shining the subject from behind. In other words, the lighting and display instrument facing each other, with the subject in between. This creates a luminous effect on the edge of the subject, while other areas are darker. Backlighting can be a natural or artificial light source. When created, the backlight is usually placed just behind the subject in a 4-point lighting setting. The back light, which turns the foreground element from the back, does not get confused with the background light, which turns on the background element (like a scene).
In the lighting design context, the backlight is sometimes called hair or shoulder light , because when turning on the actor or actress, it creates a backlight of the subject's hair shine if her hair is blurry. This can create an angel halo type effect around the head. Filmmakers sometimes use this to show that the actor is either fine or pure . Television production often uses this effect in soap operas, where it has become a kind of genre cliche. Sometimes also called kicker or light rim .
Backlight helps separate subject and background. Live theater lighting designs often use backlighting to give a three-dimensional look more to the actor or set element, when the front lighting alone will provide a flat, two-dimensional view. In chiaroscuro effects in painting, such as wax paintings by Joseph Wright of Derby ( illustrations, left ), backlighting helps separate subjects in the foreground and emphasizes depth.
In photography, the back lamp (often sun) that is about sixteen times stronger than the key light produces silhouettes. Flash content used with subjects with backlight produces even more illumination.
The vertical angle of the back light can change its effect. A low angle can make light hit the camera lens, causing the lens flare. A high angle can make the subject's nose extend out of the shadow of the head mostly vertically, producing a possible spotlight in the center of the face.
