The Lightening Effect

This effect can add electrifying lightening bolts to your images.

To add a single bolt set the number of sources to 1, set the radius to 0 and choose the start position with the sliders. Choose the angle too.

To add (for example) a ring of bolts around an eye set number of sources to 6, the radius to about 5% and use the position sliders to move the center of the lightning to the eye in your image.
