Free: Knoll Screen.

Knoll Screen is a transfer mode similar to the Screen Logic Ops that's now built into AutoDesk Advanced Systems. This spark simulates the practice of double exposing two pieces of positive film.

By multiplying the inverse of the source and target clip's color channels, light values accumulate but don't clip, and black remains transparent. No alpha channel is used. Screen very elegantly composites 'light' events, such as flares, sparks, reflections, lightning, fire, and explosions.

Another example of the Lens Flare Pro spark.

We offer Knoll Screen as a free downloadable Spark for users of older AutoDesk Advanced Systems. The spark is also great for users who need the opacity control that is missing in the built-in Logic Ops. NOTE: We do not provide technical support for this free product.
