Gry Garness is a makeup artist turned retoucher/photoshop consultant from Norway. I wasn't familiar with her photoshop tutorials until I came across this video the other day, and I must say I'm pretty impressed with her articulate approach to complicated techniques. In this video, Gry teaches some interesting liquify techniques on an image by Derek Cooper. Instead of simply using the lossy liquify tool, Gry shows you how you can use warp and puppet warp selections which give you the ability to go back and change any transforms down the road. The results are pretty amazing and it's always good to know a few different ways to accomplish the same overall outcome.
