Poster Edges

This filter transforms your image into a poster by converting full-color or grayscale images into reduced color versions by combining similar colors into bands of a single hue, like the Photoshop Posterize command. However, Poster Edges outlines all the prominent edges with black, giving the photo a hand-drawn look.

Of course, the original non-electronic poster effect was created to allow simulating continuous tone images without actually using detailed halftones. The broad bands of color could each be printed on a separate run through a sheet-fed press at a relatively low cost. Posters were often created in this way for circuses, plays, and, later, motion pictures. Even when halftoning was a common and inexpensive process, poster printing techniques were an economical way to produce very large posters on thick stocks.

Poster Edges gives you three controls, allowing you to adjust the relative thickness of the black lines used to outline the edges, and specify their darkness or intensity. A third slider lets you specify the number of tones used to produce the effect. Figure 8.25 shows the Fresco and Poster Edges filter effects.
