Ray. I was able to duplicate the result of the Sketch Effect action, using this photo to start with http://www.wga.hu/frames-e.html?/html/b/botticel/5allegor/33birth.html
. I used the Sketch and Color filter in FilterForge. The Sketch and Color filter in Filter Forge is based on a standard Photoshop technique. If you want to try it in Photoshop, here is the basic technique. If you want to try this in Photoshop,
Preprocess: Lighten the photo using the middle slider in Levels set to 1.57.
Technique: Copy background to new layer, desaturate copy, copy desaturated layer to new layer, invert, set to color dodge or linear dodge (whichever makes it pure white), then Gaussian Blur the top layer.
Post Process: Add a Levels layer mask and clip the black point.
Thing is though, it's a pain to do this technique in Photoshop. Actions are easier. So is FilterForge.
