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: The Lighting Effects filter works
only on RGB images.
Choose Filter >
Render > Lighting Effects.
For Style, choose a style.
For Light Type, choose a type. If you’re using multiple
lights, select and deselect On to turn individual lights on and
off.
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.
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.
To use a texture fill, choose a channel for Texture Channel.
