Today’s post shows off a simple example of using the Watershed Sketch image operation effect. Watershed Sketch takes an image input and can generate a variety of colored sketch effects. While today’s post will use the Watershed Sketch effect to generate a raster sketch image, you can also use Watershed Sketch to generate bezier paths that can then be painted in by a paint synthesizer preset if you want to produce a wider range of stylistic sketch effects with more sophisticated paint fill for the individual sketch lines that the Watershed Sketch generates.
The example sketch effect shown above was generated by running the WatershedSketch effect twice with different parameter settings and adding a sketch mass for defining the edges. The paint action sequence (PASeq) used to generate the overall effect is shown below and you can download it here. Watershed.paseq
