Light wrap allows the brightness of a selected layer to brighten the edges of the keyed layer. You can often improve composites using light wrap, which enables light from another layer to bleed onto the keyed layer. This helps to realistically embed the keyed subject into the surrounding scene, since the edges of the keyed layer are modified based on the specific brightness/color of the pixels behind them.
- Source Layer: Choose the layer used to generate the light wrap.
- Radius: Defines the distance, in pixels, to which the light rap will reach into the keyed layer. The effect is feathered within this distance, so the effect will be strongest at the edge of the keyed layer, and fade as it reaches farther into the layer.
- Opacity: Adjust the overall intensity of the light wrap. 1.00 gives the strongest results, while 0.00 makes the effect completely transparent.
- Blend: Select the blend mode used to apply the light wrap onto the keyed layer. The most commonly used settings are:
- Lighten: The default setting, which works best in the majority of cases. Only areas where the background layer is lighter than the keyed layer will have any effect.
- Screen: For very bright backgrounds, using screen can be helpful for transferring that brightness onto the edges of the keyed layer.
- Soft Light: When working with very dark backgrounds, this option can help to softly darken the edges of the keyed layer, and create a more convincing composite.
