| In Photoshop, create a grayscale-mode gradient. |
| In Photoshop, create a grayscale-mode file containing a gradient that will control the Gradient Wipe transition for a separate solid red layer. You can create a simple gradient using Photoshop's Gradient palette and Gradient tool, or paint freeform gradient shapes using Photoshop's brush, airbrush, blur, or smudge tools. |

| The Gradient Wipe effect uses the luminance (brightness) values of each pixel in a gradient layer to control when pixels of another layer appear. Pixels corresponding to lighter areas appear first, then pixels corresponding to a darker areas appear. In this example, we painted light and dark areas so that the red layer would first reveal its pixels along thin streaks descending from the top (lighter pixels). As time progresses, we want the rest of the red layer to be revealed progressively from top to bottom (darker pixels), following the streaks that appeared earlier. Note that when the Gradient Wipe effect is halfway through its animation, After Effects displays any layer pixels that correspond to gradient pixels with lightness values from 100% to 50%, as indicated by the blue line below (The blue line is displayed for clarity only, and doesn't appear in the program). |

| Tip: Another great way to create a freeform gradient is by using the Gradient Mesh tool in Adobe Illustrator. |
