Stylize

The Stylize filter family offers some wonderful effects. They are creative, and you can use them to add final effects or touches to an image. This section touches on the most interesting of the filters, including the Find Edges filter, the Glowing Edges filter, and the Wind filter.

Find Edges, Glowing Edges, and Trace Contour

These three effects sound as if they should look alike. They actually do look somewhat alike, with Glowing Edges and Find Edges being much more dramatic than Trace Contour. The Find Edges filter removes most of the colors from the object and replaces them with lines around every edge contour. The color of the lines depends on the value at that point on the original object, with lightest points in yellow, scaling through to the darkest points, which appear in purple. The picture looks like a rather delicate-colored pencil drawing of itself. It works best, naturally, on photos that have a lot of detail for it to find. In Figure 16.17, I've applied it to a digital photo of one of Miami's Art Deco landmark buildings. Find Edges sometimes becomes more interesting if you apply it more than once to the same picture. If you apply it once and don't like the result, try it again before you move on to a different filter.
