Photoshop Wave Filter

Photoshop Wave Filter is one of filter in Distort Filter group. Wave Filter creates an undulating pattern on a selection, like ripples on the surface of a pond. it’s works in a similar way to the Ripple filter, but with greater control.

You can access Wave Filter by choosing Filter » Distort » Wave to display the Wave dialog box. Wave Filter include following options:

• Number of Generators: The number of wave to be generate. Value can be 1 to 999.
• Wavelength: The Wave filter produces random results by varying the number length of waves between minimum and maximum values, which can range from 1 to 999.
• Amplitude: The height of the waves, random between minimum and maximum values, which can range from 1 to 999.

Max. Wavelength: 120 Max. Amplitude: 35

Max. Wavelength: 120 Max. Amplitude: 115
Max. Wavelength: 350 Max. Amplitude: 35

Max. Wavelength: 350 Max. Amplitude: 115

Note: With all other parameters set according to the specifications at the bottom of the sample, increasing Wavelength creates a larger horizontal distance between the peaks of waves. Increasing Amplitude creates a higher wave peak.

• Scale: You can scale the effects of the Wave filter between 1 and 100 percent horizontally and vertically. All the effects in sample above use only Vertical Scale, with Horizontal Scale set at the minimum of 1 percent. Increasing Horizontal Scale would make the waves go back and forth as well as up and down.
• Type: You can select from three kinds of waves. As shown below:
  • Sine: Produces standard sine waves that rise and fall smoothly in curves, just like real waves.
  • Triangle: Creates zigzags that rise and fall in straight lines, like the edge of a piece of fabric cut with pinking shears.
  • Square: Has nothing to do with waves at all, but rather organizes an image into a series of rectangular groupings, reminiscent of Cubism.

Type: Square Max. Wavelength: 120 Max. Amplitude: 35
Type: Triangle Max. Wavelength: 120 Max. Amplitude: 35
Type: Square Max. Wavelength: 20 Max. Amplitude: 70
Type: Triangle Max. Wavelength: 20 Max. Amplitude: 35

Note: The effects of the unsmooth Triangle and Square types, using relatively high Wavelength and low Amplitude values (top two examples) versus relatively low Wavelength and high Amplitude values (bottom two examples).

• Randomize: The Wave filter is random by nature. If you don’t like the effect you see in the preview box, click the Randomize button to stir things up a bit. You can keep clicking the button until you get an effect you like.
• Undefined Areas: The Wave filter distorts a selection to the extent that gaps may appear around the edges. You can fill those gaps either by repeating pixels along the edge of the selection, as in the figures, or by wrapping pixels from the left side of the selection onto the right side and pixels from the top edge of the selection onto the bottom.
