ADOBE PHOTOSHOP CS2 

The filters in the Pixelate submenu sharply define a selection by clumping pixels of similar color values in cells. 

Simulates the effect of using an enlarged halftone screen on each channel of the image. For each 

channel, the filter divides the image into rectangles and replaces each rectangle with a circle. The circle size is propor­
tional to the brightness of the rectangle. See also “To use the Color Halftone filter” on page 521. 

Clumps pixels into a solid color in a polygon shape. 

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. 

Creates four copies of the pixels in the selection, averages them, and offsets them from each other. 

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.

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.

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.

Choose Filter > Pixelate > Color Halftone.

Enter a value in pixels for the maximum radius of a halftone dot, from 4 to 127.

Enter a screen-angle value (the angle of the dot from the true horizontal) for one or more channels:

For Grayscale images, use only channel 1. 

For RGB images, use channels 1, 2, and 3, which correspond to the red, green, and blue channels. 

For CMYK images, use all four channels, which correspond to the cyan, magenta, yellow, and black channels. 

Click Defaults to return all the screen angles to their default values. 

Click OK. 

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. 

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. When you apply the Clouds filter, the image data on the active layer is replaced. 

Uses randomly generated values that vary between the foreground and background 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. When you apply the 
Difference Clouds filter, the image data on the active layer is replaced. 

Creates the look of woven fibers using the foreground and background colors. You use the Variance slider to 

control how the colors vary (a low value produces long streaks of color, and a high value results in very short fibers
