Liquify effect
The Liquify effect lets you push, pull, rotate, enlarge and shrink areas in a layer. Several Liquify tools 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.
You can limit the area of a layer you distort using Freeze Area Mask. Use the Reconstruction mode to lessen or undo
distortions you’ve created.
The Liquify effect can extend beyond the boundaries of the target layer. This is useful when the target layer is smaller
than the composition.
This effect works with 8-bpc and 16-bpc color.

Mask properties for the Liquify effect
Freeze Area Mask
Determines the area of the image in which the distortion is affected by mask opacity and feather
settings. 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 area within the mask is affected by the distortion. When Mask Opacity is set to
100%, the area within the mask is not affected by the distortion; when it’s set to 50%, the area within the mask is
somewhat affected. If you set the 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 non-masked area.
