• 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 to fully or partially reverse the distortions or to change the image in new ways.
Undo distortions with the Liquify effect
Use the Reconstruction tool and its modes to reverse distortions or redo them in new ways.
1 Select the Reconstruction tool, and then choose a mode from the Reconstruction Mode pop-up menu:
Revert Changes unfrozen areas back to their predistorted state.
Displace Reconstructs unfrozen areas to match the displacement at the starting point for the reconstruction. You
can use Displace to move all or part of the preview image to a different location.
Amplitwist Reconstructs unfrozen areas to match the displacement, rotation, and overall scaling that exist at the
starting point.
Affine Reconstructs unfrozen areas to match all local distortions that exist at the starting point, including
displacement, rotation, horizontal and vertical scaling, and skew.
2 Drag the area to restore. The restoration occurs more quickly at the brush center.
Magnify effect
The Magnify effect enlarges all or part of an image. This effect can act like a magnifying glass placed over an area of
the image, or you can use it to scale the entire image far beyond 100% while maintaining resolution.
This effect works with 8-bpc color.
