Liquifying a layer
The Liquify command lets you add a melted look to the image. In this part of the lesson, you’ll make the metal grille look as if it has melted from one side to the other.
The Liquify filter in Photoshop 7.0 includes enhancements over previous versions. If you think you’ll want to experiment with other Liquify effects after you finish the next procedure, save a copy of your 11Start.psd file now (choose File > Save As and give the copy a different name, such as 11Testing.psd), and then close it and reopen your 11Start.psd file to continue working.
Rasterizing the mask
Before you can apply the Liquify feature to the metal grille, you must rasterize its vector mask and merge the mask and image to create just one image.
