desired for a maximum of 16 lights.
To save a preset, click Save, name the style, and click OK. Saved presets include all the settings for each light and appear in the Style
menu whenever you open the image.
To delete a preset, choose it, and then click Delete.
Apply a Texture channel
In the Lighting Effects workspace, the Texture channel lets you control lighting effects using grayscale images (called bump maps). You add
bump maps to the image as alpha channels. You can add any grayscale image to your image as an alpha channel, or create an alpha channel
and add texture to it. For an embossed text effect, use a channel with white text on a black background, or vice versa.
1. If necessary, add an alpha channel to your image. Do one of the following:
To use a texture based on another image (for example, fabric or water), convert that image to grayscale, then drag the grayscale
channel from that image into the current image.
Drag an existing alpha channel from another image into the current image.
Create an alpha channel in your image, then add texture to it.
2. In the Lighting Effects workspace, choose a channel from the Texture menu in the Properties dialog box. (Choose either an alpha channel
you’ve added or the image’s Red, Green, or Blue channel.)
3. Drag the Height slider to vary the texture from Flat (0) to Mountainous (100).
