In lighting design, backlighting is the process of illuminating the subject from the back. In other words, the lighting instrument and the viewer face each other, with the subject in between. This creates a glowing effect on the edges of the subject, [1] while other areas are darker. The backlight can be a natural or artificial source of light.

A traditional, front-illuminated digital camera is constructed in a fashion similar to the human eye, with a lens at the front and photodetectors at the back. This traditional orientation of the sensor places the active matrix of the digital camera image sensor—a matrix of individual picture elements—on its front surface and simplifies manufacturing.
Backlight is a form of illumination used in liquid crystal displays (LCDs). Backlight may also refer to: Backlight, a 2010 Portuguese-American mystery film; Backlight, a 2007 Dutch documentary television program; Backlighting (lighting design), the process of illuminating a subject from the back
A typical four-point lighting setup. A background light is used to illuminate the background area of a set.The background light will also provide separation between the subject and the background. [1]
Alternative design is the "constant current" design where each parallel circuit of several SMDs includes a small integrated circuit to provide a fixed current to that group of LEDs, within a wide range of applied voltages. This allows the strip to operate at the same power level and brightness along its entire length, or with some variation in ...
An LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold cathode fluorescent (CCFL) backlighting. [1] LED-backlit displays use the same TFT LCD ( thin-film-transistor liquid-crystal display ) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.
The key light, as the name suggests, shines directly upon the subject and serves as its principal illuminator; more than anything else, the strength, color and angle of the key determines the shot's overall lighting design. In indoor shots, the key is commonly a specialized lamp, or a camera's flash.
