Backlighting (lighting design)

(重定向自Back light)
Three Persons viewing the Borghese Gladiator by candlelight, by Joseph Wright of Derby, 1765
Using backlighting, this portrait is improved by not allowing the harsh sunlight to cast hot spots on the faces AND by ringing the couple with an outlining effect, thus separating them from the background. A fill flash on the camera adds the required uniform illumination to the areas shaded from the sun.

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, while other areas are darker. The backlight can be a natural or artificial source of light. When artificial, the back light is usually placed directly behind the subject in a 4-point lighting setup. A back light, which lights foreground elements from the rear, is not to be confused with a background light, which lights background elements (such as scenery).
