Mask properties
Freeze Area Mask Determines the area of the image in which mask opacity and feather settings affect the distortion. Areas outside the mask are
distorted; areas within the mask are distorted according to Mask Opacity and Mask Feather settings.
Mask Opacity Determines how the distortion affects the area within the mask. If Mask Opacity is set to 100%, the distortion doesn't affect the
area within the mask; if it's set to 50%, the area within the mask is somewhat affected. If you set Mask Opacity to 100%, make sure to feather the
mask to prevent jagged edges on the mask.
Mask Feather The width of the feather used to blend pixels between the masked area and the nonmasked area.
Tools
Warp Pushes pixels forward as you drag.
Turbulence Smoothly scrambles pixels. This setting is useful for creating fire, clouds, waves, and similar effects.
Twirl Clockwise Rotates pixels clockwise as you hold down the mouse button or drag.
Twirl Counterclockwise Rotates pixels counterclockwise as you hold down the mouse button or drag.
Pucker Moves pixels toward the center of the brush area as you hold down the mouse button or drag.
Bloat Moves pixels away from the center of the brush area as you hold down the mouse button or drag.
Shift Pixels Moves pixels perpendicular to the stroke direction.
Reflection Copies pixels to the brush area.
Clone Copies the distortions from around a source location to the current mouse location. Set the source location by Alt-clicking (Windows) or
Option-clicking (Mac OS) the source point.
Reconstruction Reverses distortions or applies them in different ways.
Distort an image with the Liquify effect
1. Select the layer, and choose Effect > Distort > Liquify.
2. In the Layer panel, create a mask to freeze areas of the image, and then set mask properties.
3. In the Effect Controls panel do the following:
Choose the mask you created from the Freeze Area Mask pop-up menu.
Specify a brush size and brush pressure. A low brush pressure makes changes occur more slowly, so it's easier to stop them at exactly
the right moment.
Specify a turbulent jitter to control how tightly the Turbulence tool scrambles pixels.
Select View Mesh under the View Options control.
Set a distortion mesh offset if desired.
Drag the Distortion Percentage slider to specify the amount of distortion.
4. Use the tools to distort the preview of the image.
5. Use the Reconstruction tool
Undo distortions with the Liquify effect
Use the Reconstruction tool and its modes to reverse distortions or redo them in new ways.
Video Copilot website
to fully or partially reverse the distortions or to change the image in new ways.
