Liquifying an Image
Chapter Lessons
• Use the Liquify tools to distort an image• Learn how to freeze and thaw areas• Use the mesh feature as you distort an image
Distorting Images
• Use the Liquify feature to modify images• 8 tools in the Liquify feature are available to
modify an image– 6 distortion tools – 2 non-distortion tools
Using the Liquify Feature
• Use to make parts of an image appear as if it has been melted
• Apply the Liquify distortions with a brush– Modify brush size and pressure
Freezing and Thawing
• Use the two non-distortion tools for freezing and thawing areas within the image
• Freezing– Protects an area from editing
• Thawing– Thaws a frozen area to permit editing
Use the Liquify Tools to Distort an Image
• Apply distortions to any rasterized layer• Contents of the active layer appear in a large
preview window in the Liquify dialog box
Opening the Liquify Dialog Box
• Select the layer containing the items to distort• Click Filter on the Menu bar• Click Liquify

Learn How to Freeze and Thaw Areas
• Use the Freeze and Thaw Tools in the Liquify dialog box to:– Freeze areas within an image so that Liquify tools
leave them unaffected– Thaw frozen areas and then edit them
Freezing Image Areas
• To selectively freeze areas– Paint them with a pointer
• By default, frozen areas are painted in red • A different color for frozen areas can be
applied
Frozen Image Example
Purple area is frozen and not affected by
distortions to other areas
Reconstructing Distortions
• Individual distortions made with the Liquify feature do not appear in the History panel– These distortions cannot be undone
• Use the History panel to delete the effects of an entire Liquify session
• Reconstruct using one of eight reconstruction modes
Reconstruction ExampleBefore

Reconstruction Methods
• Click Revert in the Liquify dialog box• Choose the Revert mode, then click
Reconstruct in the Liquify dialog box• Click the Reconstruct tool, choose the Revert
mode, then drag the brush over distorted areas in the Liquify dialog box
Reconstruction Methods
• Click the Cancel button in the Liquify dialog box
• Make distortions in the Liquify dialog box, then drag the Liquify state to the Delete current state button on the History panel
Use the Mesh Feature as you Distort an Image
• Turn on the mesh to see the effects of distortions• Definition of the mesh:– Series of horizontal and vertical gridlines
superimposed on the preview • Control the mesh using the View Options section
in the Liquify dialog box
Image with Mesh Showing
Changing Mesh Display
• Modify the appearance of the mesh:– Display mesh in another color– Display mesh in larger or smaller gridlines
Modified Mesh Display
Visualizing Distortions
• View gridlines while making distortions – Check if symmetrical objects have equally
symmetrical distortions
Viewing Distortions
• Distort imagery with companion layers visible• Two methods:– Select the Backdrop check box in the Liquify dialog
box, then select which layers should be visible with the selected layer
– Click the highest layer on the Layers panel, click the Layers panel list arrow, then click Merge Visible
