Trang 3The Liquify Tool options control the brush tip Since all the Liquify com-mands are executed with a brush, it's important to understand how you control the brush tip When you apply the brush stroke, the faster you drag the mouse, the less effect is applied to the image; if you drag slowly, you gain more control and the effect is more intense Practice dragging the cursor over the image to produce different effects, and if you make a mistake, don't forget the undo key—Ctrl+Z (Win), A+Z (Mac)
