Crystallize
Clumps pixels into a solid color in a polygon shape.
Facet (Photoshop)
Clumps pixels of solid or similar colors into blocks of like-colored
pixels. You can use this filter to make a scanned image look hand painted or to make a
realistic image resemble an abstract painting.
Fragment (Photoshop)
Creates four copies of the pixels in the selection, averages them,
and offsets them from each other.
Mezzotint
Converts an image to a random pattern of black-and-white areas or of fully
saturated colors in a color image. To use the filter, choose a dot pattern from the Type
menu in the Mezzotint dialog box.
Mosaic (Photoshop)
Clumps pixels into square blocks. The pixels in a given block are the
same color, and the colors of the blocks represent the colors in the selection.
Pointillize
Breaks up the color in an image into randomly placed dots, as in a pointillist
painting, and uses the background color as a canvas area between the dots.
Render filters
The Render filters create 3D shapes, cloud patterns, refraction patterns, and simulated
light reflections in an image. You can also manipulate objects in 3D space, create 3D
objects (cubes, spheres, and cylinders), and create texture fills from grayscale files to
produce 3D-like effects for lighting.
3D Transform
Maps images to cubes, spheres, and cylinders, which you can then rotate
in three dimensions. For more information, see
“Transforming objects in three dimen-
sions” on page 186
.
Clouds
Generates a soft cloud pattern using random values that vary between the
foreground and the background colors. To generate a more stark cloud pattern, hold
down Alt (Windows) or Option (Mac OS) as you choose Filter> Render > Clouds.
Difference Clouds
Uses randomly generated values that vary between the foreground
and back-ground color to produce a cloud pattern. The filter blends the cloud data with
the existing pixels in the same way that the Difference mode blends colors. The first time
you choose this filter, portions of the image are inverted in a cloud pattern. Applying the
filter several times creates rib and vein patterns that resemble a marble texture.
Lens Flare
Simulates the refraction caused by shining a bright light into the camera lens.
Specify a location for the center of the flare by clicking anywhere inside the image
thumbnail or by dragging its cross hair.
Lighting Effects
Lets you produce myriad lighting effects on RGB images by varying 17
light styles, 3 light types, and 4 sets of light properties. You can also use textures from
grayscale files (called
bump maps
) to produce 3D-like effects and save your own styles for
use in other images.
Texture Fill
Fills a selection with a grayscale file or part of a file. To add the texture to
the document or selection, you open the grayscale document you want to use as the
texture fill.
