Blur filters Soften a selection or an image. Blur
filters are useful for retouching. They smooth
transitions by averaging the pixels next to the hard
edges of defined lines and shaded areas in an
image.
Note: To apply a Blur filter to the edges of a layer, be
sure to turn off the Preserve Transparency option in
the Layers palette.
Brush Strokes filters
Like the Artistic filters, the
Brush Strokes filters give a painterly or fine-arts
look using different brush and ink stroke effects.
Some of the filters add grain, paint, noise, edge
detail, or texture to an image for a pointillist effect.
D
istort filters
Geometrically distort an image,
creating 3-D or other reshaping effects. Note that
these filters can be very memory intensive. For
information on the Glass filter, see “Using texture
and glass surface controls” on page 304. For more
on the Displace filter, see “Defining undistorted
areas” on page 304 and online help.
N
oise filters Add or remove noise, or pixels with
randomly distributed color levels. This helps to
blend a selection into the surrounding pixels.
Noise filters can create unusual textures or remove
problem areas, such as dust and scratches, from an
image. The Add Noise filter can be used to reduce
banding in feathered selections or graduated
fills or to give a more realistic look to heavily
retouched areas.
For more on the Dust & Scratches filter, see
the online help.
Pixelate filters Sharply define a selection by
clumping pixels of similar color values in cells.
For more on the Color Halftone filter, see
the online help.
Render filters Create 3-D shapes, cloud patterns,
refraction patterns, and simulated light reflections
in an image. You can also manipulate objects in 3-
D space, create 3-D objects (cubes, spheres, and
cylinders), and create texture fills from grayscale
files to produce 3-D-like effects for lighting. For
information on the 3D Transform filter, see
“Transforming objects in three dimensions” on
page 187.
For more information on the Lighting
Effects filter, see the online help.
When using the Clouds filter, generate a
more stark cloud pattern by holding down
Alt (Windows) or Option (Mac OS) as you
choose Filter > Render > Clouds.
Sharpen filters
Focus blurry images by increasing
the contrast of adjacent pixels. They include the
Sharpen Edges and Unsharp Mask filters, which
find and sharpen areas where significant color
changes occur (such as at the edges). The Unsharp
Mask filter is commonly used for high-end color
correction (see “Step 6: Sharpen the image” on
page 128).
