Find Edges

The Find Edges filter produces some dramatic effects, similar to drawings created with colored pencils. There are no controls or dialog boxes. This filter makes a great springboard for combining several filters or using other controls to generate outrageous variations. Use the Image > Adjustments > Hue/Saturation dialog box's sliders to warp the colors in your edge-enhanced image, juice up the saturation, or lighten/darken the effect. Pixelate your image, or merge it with a copy of the original image, adjusting the Opacity slider in the Layers Palette to combine varying percentages of the unaltered and edge-enhanced versions. Figure 8.30 shows the Sumi-e and Find Edges filters applied to our portrait.
