Lens Flares

The Lens Flare effect simulates artifacts that are produced by the internal light transport inside a real-world camera lens. This includes light reflection and scattering.

The artifacts are generally aligned along the line defined by the original bright spot and the center of the screen. The most noticeable artifact is often exactly symmetrical to a real spot light with respect to the center of the screen.
