The Plaster effect creates an image that appears to be molded from three-dimensional plaster. The dark areas of the image
appear raised, while light areas appear lower. This is an effect that is particularly useful for images consisting of text
or simple, high-contrast graphics.
By default, this effect produces a monochrome (gray-scale) image.
