Brush Stroke Filters; Distort Filters - Adobe 13102498 - Photoshop CS3 - Mac User Manual

controls how much the tonal values of neighboring pixels must diverge from the center pixel value before being part
of the blur. Pixels with tonal value differences less than the Threshold value are excluded from the blur.

Brush Stroke filters

Like the Artistic filters, the Brush Stroke 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. All the Brush Stroke filters can be applied
through the Filter Gallery.
Accentuates the edges of an image. When the edge brightness control is set to a high value, the
Accented Edges
accents resemble white chalk; when set to a low value, the accents resemble black ink.
Repaints an image using diagonal strokes, with lighter and darker areas painted in strokes going in
Angled Strokes
opposite directions.
Preserves the details and features of the original image while adding texture and roughening the edges
Crosshatch
of the colored areas with simulated pencil hatching. The Strength option (with values from 1 to 3) determines the
number of hatching passes.
Paints dark areas with short, tight, dark strokes, and lighter areas with long, white strokes.
Dark Strokes
Redraws an image with fine narrow lines over the original details, in pen-and-ink style.
Ink Outlines
Replicates the effect of a spatter airbrush. Increasing the options simplifies the overall effect.
Spatter
Repaints an image, using its dominant colors, with angled, sprayed strokes of color.
Sprayed Strokes
Paints an image in Japanese style, as if with a fully saturated brush applied to rice paper. Sumi-e creates soft,

blurred edges with rich, inky blacks.

Distort filters

The Distort filters geometrically distort an image, creating 3D or other reshaping effects. Note that these filters can
be very memory intensive. The Diffuse Glow, Glass, and Ocean Ripple filters can be applied through the Filter
Gallery.
Renders an image as though it were viewed through a soft diffusion filter. The filter adds see-through
Diffuse Glow
white noise, with the glow fading from the center of a selection.
Uses an image, called a displacement map, to determine how to distort a selection. For example, using a
Displace
parabola-shaped displacement map, you can create an image that appears to be printed on a cloth held up by its
corners.
Makes an image appear as if it were being viewed through different types of glass.You can choose a glass effect
Glass
or create your own glass surface as a Photoshop file and apply it. You can adjust scaling, distortion, and smoothness
settings. When using surface controls with a file, follow the instructions for the Displace filter.
The Lens Correction filter fixes common lens flaws such as barrel and pincushion distortion,
Lens Correction
vignetting, and chromatic aberration.
Adds randomly spaced ripples to the surface of the image so that it appears to be underwater.
Ocean Ripple
Squeezes a selection. A positive value up to 100% shifts a selection toward its center; a negative value up to –
Pinch
100% shifts a selection outward.
Converts a selection from its rectangular to polar coordinates, and vice versa, according to a
Polar Coordinates
selected option. You can use this filter to create a cylinder anamorphosis—an art form popular in the 18th century—
in which the distorted image appears normal when viewed in a mirrored cylinder.
