Glow (PB only)This effect finds the brighter parts of an image, and then brightens those and surrounding pixels to create a diffuse, glowing halo. It can also simulate overexposure of brightly lit objects. Base the glow on either the original colors of the image or on its alpha channel. Glows based on alpha channels produce diffuse brightness only at the edges of the image, between the opaque and transparent regions. You can also use this effect to create a gradient glow between two colors and to create multicolor effects with looping. Rendering this effect at Best quality can change the appearance of the layer. This is especially true if you are using Adobe Photoshop arbitrary maps to color your glows. Glow supports Photoshop arbitrary map files (.amp), which are created and saved from the Curves dialog box. Be sure to preview this effect at Best quality before rendering. ![]() For more information, see the After Effects product section on Adobe's Web site. |
