Ripple
Creates an undulating pattern on a selection, like ripples on the surface of a pond. For greater control, use
the Wave filter. Options include the number and size of ripples.
Shear
Distorts an image along a curve. Specify the curve by dragging the line in the box. You can adjust any point
along the curve. Click Default to change the curve back to a straight line. In addition, you choose how to treat undis
torted areas.
torted areas.
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.
Twirl
Rotates a selection more sharply in the center than at the edges. Specifying an angle produces a twirl pattern.
Wave
Works much as the Ripple filter does, but with greater control. Options include the number of wave gener
ators, the wavelength (distance from one wave crest to the next), the height of the wave, and the wave type: Sine
(rolling), Triangle, or Square. The Randomize option applies random values. You can also define undistorted areas.

To replicate wave results on other selections, click Randomize, set Number Of Generators to 1, and set the minimum
and maximum Wavelength and Amplitude parameters to the same value.
and maximum Wavelength and Amplitude parameters to the same value.
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 specify how to
displace the pixels: Pond Ripples displaces pixels to the upper left or lower right, Out From Center displaces pixels
toward or away from the center of the selection, and Around Center rotates pixels around the center.

To use the Displace filter
The Displace filter shifts a selection using a color value from the displacement map—0 is the maximum negative
shift, 255 the maximum positive shift, and a gray value of 128 produces no displacement. If a map has one channel,
the image shifts along a diagonal defined by the horizontal and vertical scale ratios. If the map has more than one
channel, the first channel controls the horizontal displacement, and the second channel controls the vertical
displacement.

the image shifts along a diagonal defined by the horizontal and vertical scale ratios. If the map has more than one

Choose Filter > Distort > Displace.
2
Enter the scale for the magnitude of the displacement.
When the horizontal and vertical scale are set to 100%, the greatest displacement is 128 pixels (because middle gray
produces no displacement).
produces no displacement).

If the displacement map is not the same size as the selection, specify how the map fits the image—select Stretch
To Fit to resize the map or Tile to fill the selection by repeating the map in a pattern.
4
Choose Wrap Around or Repeat Edge Pixels to determine how undistorted areas of the image are treated.
5
Click OK.
6
Select and open the displacement map. The distortion is applied to the image.
