Feel free to experiment with any of the Face-Aware Liquify options to get a better sense of the possibilities for quick, easy alterations. 7. Click OK to exit Liquify. Close the document and save your changes. The Face-Aware Liquify features are available only when Photoshop recognizes a face in an image. It may not recognize a face that is turned too far away from the camera or when a face is partially covered by hair, sunglasses, or a hat shadow.
Blurring a background The interactive blurs in the Blur Gallery let you customize a blur as you preview it on your image. You’ll use an iris blur to blur the background in an image, focusing the viewer’s attention on the main attraction—in this case, the egret. You’ll apply the blur as a Smart Filter so that you can modify it later if you want to.
