This filter retains important edges and gives them a rough crosshatch appearance; the solid background color shows through the smoother areas. You can set the pencil width, stroke pressure, and paper brightness. Note: For a parchment effect, change the background color before applying the Colored Pencil filter to a selected area. Cutout The Cutout filter portrays an image as though it were made from roughly cut-out pieces of colored paper. Highcontrast images appear as if in silhouette, while colored images are built up from several layers of colored paper. You can set the tonal levels, edge simplicity, and edge fidelity. Dry Brush The Dry Brush filter paints an image using a dry brush technique (between oil and watercolor). The filter simplifies an image by reducing its range of colors to areas of common color. You can set the brush size, brush detail, and texture amount.
