Setting Mask Properties

The Liquify effect uses the mask properties to determine how to affect the image. Use Freeze Area Mask, Mask Opacity, and Mask Feather settings to control 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 the mask opacity and 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

determines the pixels at the borders of the mask used to blend the masked area into the non-masked areas. You can begin with a feather value of 10 pixels and then adjust it as appropriate.
