AV News 197 - August 2014 If you create an active selection within your working layer before opening Liquify then the Liquify filter will automatically turn your selection into a mask. This mask allows manipulation of the area within the selection while freezing the unselected area. If you wish to manipulate outside of this selected area click the 'Invert All' button under 'Mask Options' on the right hand side control panel. Note that for many editing procedures it's convenient and perhaps more intuitive to paint any required mask with the 'Freeze Mask' tool after opening the Liquify filter. The control panel shown here (in its advanced mode) is where settings are made to control the behaviour of each Liquify tool, i.e. brush size, density, pressure etc. Some settings are obvious and self explanatory although the five symbols used for 'Masking Options' require some clarification.

If an error is made during editing then these buttons can be used to restore your work, either in small controllable stages using the 'Reconstruct' button in conjunction with the 'Reconstruct Brush', or back to its original state quickly with just one click using the 'Restore All' button. Be aware however that for retouching a human figure Liquify should be used with great care, patience, and subtlety. However if using Liquify for artistic or creative purposes i.e. to alter the shape of clouds, trees, or other elements within a creative image then subtlety can be disregarded. The topmost tool in the toolbox named 'Forward Warp' is the most basic tool provided but probably the most used. This tool pushes pixels as you drag your mouse or stylus across an image. Controlling the amount of pixels movement depends on the size of brush and pressure setting selected in the contro [
