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.

light styles, light types, light properties, and a

5
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 Shiny
(high reflectance).
Material determines whether the light or the
object on which the light is cast reflects more light.
Plastic reflects the light's color, Metallic reflects the
object's color.
Exposure increases the light (positive values) or
decreases the light (negative values). 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
diffuse 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
