Face-Aware
Liquify
Consider discussing when it is
appropriate
to use Face-Aware Liquify. For e

Face-Aware Liquify may be useful for advertising or illustration, but when
adjusting
a formal or family portrait it is typically not
appropriate
to use Face-Aware Liquify
to
adjust a face so much that it is no longer an accurate
