Applying Sketch Filters
The three sketch filters that I discuss here — Charcoal, Chalk and Charcoal, and Graphic Pen — all work in the same fashion. Before you even select one of these filters from the Filter>Sketch menu, be sure to select Foreground and Background colors in the Toolbox. These colors are the ones that will be used by the sketch filters. The Background setting determines the color of the “paper” that the sketch is done on, and the Foreground setting determines the color that is used for the actual “ink” of the sketching.When the colors are set, you can access the Charcoal, Chalk and Charcoal, and Graphic Pen filters. To do so, open the Filter Gallery by choosing Filter>Sketch>Charcoal, Chalk and Charcoal, or Graphic Pen. The Filter Gallery shows you a preview of the sketch on the left and various settings on the right. (See Figure 41-1.)
Figure 41-1: The settings for each Sketch filter are pretty much the same.
The settings for each filter are pretty much the same. They include Thickness, Detail, Light/Dark Balance, and possibly Light Direction. Adjust these settings as you like to achieve a good balance between the light and dark elements. Figure 41-2 shows an original photograph and the rendering by each of the three filters.

Overall, these filters do a great job of creating charcoal and graphic pen sketches by using different drawing methods. The following sections show you how to enhance the filter effects by layering or recoloring.
