When this system variable is off, exterior daylight is turned off when photometric lighting is enabled (LIGHTINGUNITS system variable is set to 1 or 2). When on, the exposure control algorithm in the rendering acts as if there is an extremely bright light source in the scene. Therefore, the default setting of “Auto” is tied directly to the sun setting. Under special circumstances, it may be desirable to manually set this variable due to extremely bright artificial light sources or, conversely, due to a sun-lit scene that it is illuminated only by a small amount of directly visible sunlight.
