To apply the Ripple filter 1 Select a paint object. To limit the effect to a particular area, select the area where you want to apply the filter. If you don’t make a selection, the filter affects the entire image. 2 Choose Image > Filter > Other > Ripple. Adjust the settings in the Ripple dialog box, and then click OK to apply the settings and close the dialog box. To close the dialog box without changing the image, click Cancel. Ripple settings You can adjust the following settings in the Ripple dialog box. Spin The Spin value controls the effect of swirling the image around its center point. Type a number from -100 to 100 or drag the slider to set the amount and direction of spin. Positive numbers gen- erate a clockwise spin; negative numbers generate a counter-clock- wise spin. Larger values (positive or negative) increase the amount of swirling. If Spin is zero, the filter creates no ripples in the image and none of the other controls produces an effect. Frequency The Frequency value affects the number of “waves” created in the image. Type a number from 0 to 50. A large number creates more small waves; a small number creates fewer large waves. Clustering The Clustering option can create interesting interference patterns in combination with some Frequency values. In general, Fre- quency values of 15 to 50 and Spin values of 25 and higher are most effective. You can enter a Clustering value of 0 to 30. The higher the Clustering value, the more interference ripples appear between the main waves. Wave Decay The Wave Decay value softens the effect of the Fre- quency setting by dampening or stretching the waves away from the center of the image. The closer a wave is to the center of the image, the less it is stretched. Wave Decay creates the impression of blend- ing the waves farthest from the center of the disturbance, especially when Include Corners is selected. Enter a Wave Decay value of 0 to 100. The higher the value, the more the waves appear stretched toward the edge of the image. High Frequency The High Frequency option causes an approxi- mate doubling of the effect of the Frequency setting. Bullseye Mode Selecting Bullseye Mode leaves rings of unchanged original image area between the wave distortions. This
