This post discusses how to build a DualMode Paint preset that dynamically sketches a static source image with paint particles whose paint stroke trails fade out over time. The DualMode Paint preset is composed of a time particle based paint synthesizer preset along with the Fixed Color image operation for it’s Dual Op to fade the painting time particles over time. The end result is a paint animation that dynamically paints in the source features over time.
The goal for the desired paint preset for this effect is to program a set of paint time particles that sketch out source edge features over time as the particles move. I started out by reinitializing the paint synthesizer using the Reinitialize paint synthesizer macro edit command in the integrated Help browser (first gallery image below).
