In the Realistic visual style, the Graphic Display Options dialog allows you to specify a light scheme for the current view.
This functionality has 6 options that control whether the Sun, or Artificial lights, or both, are used in the scene. When Artificial lights are used, the Photographic Exposure parameter should also be used to apply a visually satisfying tone to the scene. These exposure parameters are set from the Photographic Exposure group on the Graphic Display Options dialog, and can be customized or left as default (Manual) values. These settings are similar to Exposure Parameters in the Rendering dialog.
