The Lighting Effects filter

To use the Lighting Effects filter

The Lighting Effects filter lets you produce myriad lighting effects on RGB images. You can also use textures from

grayscale files (called bump maps) to produce 3D-like effects and save your own styles for use in other images.

Note: Th

e Lighting Effects filter works only on RGB images.

1 Choose Filter > Render > Lighting Effects.

2 For Style, choose a style.

3 For Light Type, choose a type. If you’re using multiple lights, select and deselect On to turn individual lights on

and off.

4 To change the color of the light, click the color box in the Light Type area of the dialog box.

The color picker chosen in the General Preferences dialog box opens.

5 To set light properties, drag the corresponding slider for the following options:

Gloss Determines how much the surface reflects light (as on the surface of a piece of photographic paper) from

Matte (low reflectance) to Glossy (high reflectance).

Material Determines which is more reflective: the light or the object on which the light is cast. Plastic reflects the

light’s color; Metallic reflects the object’s color.

Exposure Increases (positive values) or decreases (negative values) light. A value of 0 has no effect.

Ambience Diffuses the light as if it were combined with other light in a room, such as sunlight or fluorescent light.

Choose a value of 100 to use only the light source, or a value of –100 to remove the light source. To change the color

of the ambient light, click the color box and use the color picker that appears.

To duplicate a light, Alt-drag (Windows) or Option-drag (Mac OS) the light within the preview window.

6 To use a texture fill, choose a channel for Texture Channel.
