Charcoal sketchOutlines images in black and hides all other colors. Mosaic and TileMosaic groups pixels into rectangles of the same color . In the Mosaic window, enter the width and height of the pixel, and the definition (contrast between adjacent pixels). Figure 31-12. Mosaic filter
ReliefConverts image to a relief, which has an effect like a carving or embossed paper. Figure 31-13. Relief filter
PosterizeReduces number of colors, and can create a very nice muted effect in some graphics. In the Posterize window, enter how many colors to use. Figure 31-14. Poster filter
PopartReduces and changes colors. Not a good choice for any picture that you want to still be representative. It's better for designs, backgrounds, etc. Figure 31-15. Popart filter
AgingChanges colors partially to pinks and browns, to achieve the effect of an old photograph. In the Aging window, enter the percentage to age. Figure 31-16. Aging filter
SolarizationAchieves the effect of a negative. In the Solarization window, enter the percentage controlling how much of the image will be effected. A low percentage will affect most of the image; a high percentage will affect very little of it. Select Invert to invert the pixel color, as well. Figure 31-17.
