Shear
Distorts an image along a curve. Specify the
curve by dragging the line in the box to form a
curve for the distortion. You can adjust any point
along the curve. Click Default to return the curve
to a straight line. In addition, you choose how to
treat undistorted areas. (See “Defining undis-
torted areas” on page 191.)

torted areas” on page 191.)
Spherize
Gives objects a 3D effect by wrapping a
selection around a spherical shape, distorting the
image and stretching it to fit the selected curve.
image and stretching it to fit the selected curve.
Twirl
Rotates a selection more sharply in the
center than at the edges. Specifying an angle
produces a twirl pattern.
produces a twirl pattern.
Wave
Works in a similar way to the Ripple filter,
but with greater control. Options include the
Number of Generators, Wavelength (distance
from one wave crest to the next), Amplitude, Scale
(the height of the wave), and Type: Sine (rolling),
Triangle, or Square. The Randomize option
applies random values. You can also define
Undefined Areas. (See “Defining undistorted
areas” on page 191.)

ZigZag
Distorts a selection radially, depending on
the radius of the pixels in your selection.
The Ridges option sets the number of direction
reversals of the zigzag from the center of the
selection to its edge. You also choose how to
displace the pixels: Pond Ripples displaces pixels to

displaces pixels toward or away from the center of
the selection, and Around Center rotates pixels
around the center.

Liquify filter
Lets you warp, twirl, expand, contract, shift, and
reflect areas of the image. (See “Using the Liquify
filter” on page 124.) The Liquify filter is accessible
in the Filters menu and in the Filters palette under
All filters and Distort filters.

All filters and Distort filters.
Noise filter
The Noise 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.

Add Noise
Applies random pixels to an image,
simulating the effect of shooting pictures on high-
speed film. The Add Noise filter can also be used to
reduce banding in feathered selections or
graduated fills or to give a more realistic look to
heavily retouched areas. Options include noise
distribution: Uniform distributes color values of
noise using random numbers between 0 and plus
or minus the specified value for a subtle effect;
Gaussian distributes color values of noise along a
bell-shaped curve for a speckled effect. The
Monochromatic option applies the filter to only
the tonal elements in the image without changing
the colors.
