Sketch filters
Bas Relief
The Bas Relief filter transforms an image to appear carved in low relief and lit to accent the surface variations. Dark
areas of the image take on the foreground color, light areas use the background color. You can set relief detail and
smoothness.
Chalk & Charcoal
The Chalk & Charcoal filter redraws an image’s highlights and midtones with a solid midtone gray background drawn
in coarse chalk. Shadow areas are replaced with black diagonal charcoal lines. The charcoal is drawn in the foreground
color, the chalk in the background color. You can set stroke pressure, and the charcoal and chalk areas.
Charcoal
The Charcoal filter redraws an image to create a smudged effect. Major edges are boldly drawn, and midtones are
sketched using a diagonal stroke. Charcoal is the foreground color, and the paper is the background color. You can set
the charcoal thickness, level of image detail, and light/dark balance.
Chrome
The Chrome filter gives the image a polished chrome surface using highlights as high points and shadows as low points
in the reflecting surface. You can set the level of chrome surface detail and smoothness.
After applying the Chrome filter, use the Levels dialog box to add more contrast to the image.
Comic
The Comic filter (Filter > Sketch > Comic) creates the impression that the image was hand-created by a comic artist.
The final outcome can be adjusted to include the level of detailing that you need. The main controls are to change the
range of colors (Soften), the number of colors reproduced (Shades), how the colors transition from one to another
(steepness), and the vividness of the colors (Vibrance). In addition to this, you can adjust the thickness of the pen
strokes that are used to outline shapes.
Conté Crayon
The Conté Crayon filter replicates the texture of dense dark and pure white Conté crayons on an image. The Conté
Crayon filter uses the foreground color for dark areas and the background color for light areas. You can set the level of
foreground and background emphasis, and texture options. Texture options make images appear as if they were painted
onto textures, such as canvas and brick, or viewed through glass blocks, for example.
For a more realistic effect, change the foreground color to one of the common Conté Crayon colors (black, sepia, or
sanguine) before applying this filter. For a muted effect, change the background color to white with some foreground
color added to it.
