Prerequisite: Enable the graphics processor
As a prerequisite to using Face-aware Liquify functionality, ensure that the graphics processor is enabled in your Photoshop preferences.
- Choose Edit > Preferences > Performance.
- In the Graphics Processor Settings area, select Use Graphics Processor.
- Click Advanced Settings. Ensure that Use Graphics Processor To Accelerate Computation is selected.
- Click OK.
These settings are enabled by default when you launch Photoshop for the first time. If you have questions regarding GPU usage in Photoshop, consult
this document.
Distortion tools
Several tools in the Liquify dialog box distort the brush area when you hold down the mouse button or drag. The distortion is concentrated at the center of the brush area, and the effect intensifies as you hold down the mouse button or repeatedly drag over an area.
Forward Warp tool
Pushes pixels forward as you drag.
Note:Shift-click with the Warp tool, the Push Left tool, or the Mirror tool to create the effect of dragging in a straight line from the previous point you clicked.
Reconstruct tool
Reverses the distortion you’ve already added, as you hold down the mouse button and drag.
Twirl Clockwise tool
Rotates pixels clockwise as you hold down the mouse button or drag. To twirl pixels counterclockwise, hold down Alt (Windows) or Option (Mac OS) as you hold down the mouse button or drag.
Pucker tool
Moves pixels toward the center of the brush area as you hold down the mouse button or drag.
Bloat tool
Moves pixels away from the center of the brush area as you hold down the mouse button or drag.
Push Left tool
Moves pixels to the left when you drag the tool straight up (pixels move to the right if you drag down). You can also drag clockwise around an object to increase its size, or drag counterclockwise to decrease its size. To push pixels right when you drag straight up (or to move pixels left when you drag down), hold down Alt (Windows) or Option (Mac OS) as you drag.
Distortion tool options
Brush Size
Sets the width of the brush you’ll use to distort the image.
Brush Density
Controls how a brush feathers at the edge. An effect is strongest in the center of the brush and lighter at the edge.
Brush Pressure
Sets the speed at which distortions are made when you drag a tool in the preview image. Using a low brush pressure makes changes occur more slowly, so it’s easier to stop them at exactly the right moment.
Brush Rate
Sets the speed at which distortions are applied when you keep a tool (such as the Twirl tool) stationary in the preview image. The higher the setting, the greater the speed at which distortions are applied.
Stylus Pressure
Uses pressure readings from a stylus tablet. (This option is available only when you are working with a stylus tablet.) When selected, the brush pressure for the tools is the stylus pressure multiplied by the Brush Pressure value.
