Applying Filters, Effects, and Layer Styles
Pixelate filters
The Pixelate filters sharply define an image or
selection by clumping pixels of similar color
values.
Color Halftone
enlarged halftone screen on the layer. 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.
To use the Color Halftone filter:
1 Either choose Filter > Pixelate > Color
Halftone, or use the Filters palette to apply the
Color Halftone filter. (If using the palette, select
Filter Options before applying the filter.)
2 Enter a value for the maximum radius of a
halftone dot, from 4 to 127 pixels.
3 Enter a screen-angle value between -360 and
360 (the angle of the dot from the true horizontal)
for one or more channels:
• For Grayscale images, enter a value in channel 1.
Values in the other channel text boxes do not
affect the filter.
• For color images, use channels 1, 2, 3, and 4,
which correspond to CMYK channels (Cyan,
Magenta, Yellow, and Black).
• Click Defaults to return all the screen angles to
their default values.
4 Click OK.
Crystallize
clumps of color. You can set the cell size of the
crystals in the filter options.

Redraws a layer as polygon-shaped
Redraws a layer as blocks of solid color. You
Facet
can use this filter to make a scanned image look
hand painted or to make a realistic image resemble
an abstract painting.
Redraws a layer so it appears offset and
Fragment
blurred.
Redraws a layer as a random pattern of
Mezzotint
black-and-white areas in a grayscale image, or fully
saturated colors in a color image. You can choose a
dot, line, or stroke pattern in the filter options.
Redraws a layer as square blocks of color.
Mosaic
You can set the mosaic cell size in the filter options.
Redraws a layer as randomly placed
Pointillize
dots, as in a pointillist painting, and uses the
background color in the toolbox as a canvas area
between the dots. You can set the cell size in the
filter options.
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.
Maps images to cubes, spheres, and
3D Transform
cylinders, which you can then rotate in three
dimensions. (See "Transforming objects in three
dimensions" on page 157.)
Generates a soft cloud pattern using
Clouds
random values that vary between the foreground
and the background color in the toolbar.
