Glow (Pro only)

The Glow effect finds the brighter parts of an image and then brightens those and surrounding pixels to create a diffuse, glowing halo. The Glow effect can also simulate overexposure of brightly lit objects. You can 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 the Glow effect to create a gradient glow between two colors and to create multicolor effects with looping.

Rendering the Glow 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. Be sure to preview your Glow effect at Best quality before you render it.
