Using a Lighting Effects texture The Texture Channel control in the Lighting Effects dialog box lets you manipulate how light reflects off an image. You can create a texture effect based on the light and dark areas of the red, green, and blue color information in your image. You can also choose to use the layer transparency of the active layer to create a texture effect. To use the Texture Channel in the Lighting Effects dialog box: 1 In the Lighting Effects dialog box, choose a color from the Texture Channel pop-up menu. 2 Select White is High to raise the light parts of the channel from the surface. Deselect this option to raise the dark parts. 3 Drag the Height slider to vary the depth of the texture from Flat (0) to Mountainous (100). 4 Click OK.
