The Lighting, Exposure and Lighting Composite nodes

---

To set up lighting effects in Director, you use the Lighting or Exposure node, and the Lighting Composite node:

• The Lighting node composites its inputs, just like any other node. It can then blur and tint this image, which is useful for lighting effects such as a "glow" or "halo".

The node also sets a lighting style (None, Backlight, Alt-Backlight, Ambient or Highlight), and the exposure to use. However, it does not actually do the lighting. For this, you must connect the Lighting node's output to the input of a Lighting Composite node.

• The Exposure node is exactly the same as the Lighting node, except that it cannot blur and tint its input. You should use this node if you do not need to blur and tint, as it is more efficient than disabling the Lighting node's blurring and tinting.

• The Lighting Composite node composites its inputs, applying any lighting effects that you have specified in Lighting or Exposure nodes. It will ignore any elements of the scene that are not connected to its input.
