How do I put light behind an object?

Putting light behind an object can be achieved in one of two ways.
- Create a Photoshop selection prior to applying light. Once Light is applied, it will only show up only in the areas of the selection.
- Create a selection inside of Light. Your results will be dependent on there being some type of difference between the object you are trying to isolate and the background.
- Change the Shape>Blend Mode from Shape Only to Multiply. The Multiply blend mode only adds the shape in the areas of the selection.
- Use the Selection controls to isolate where the light will appear.
- Set the Selection>Extract On value to give you the best separation between the object and the light.
- Change the Selection>Position parameter if you want to select different values to be used for the light.
- Increase the Selection>Range value to add more light into the scene. Decrease for less light.
- Increase the Selection>Blur parameter to soften the transition areas of the light.
