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.
Lighting Effects types
You can choose from several lighting types:
Omni Shines light in all directions from directly above the image—like a light bulb over a piece of paper.
Directional Shines light from far away so that the light angle doesn’t change—like the sun.
Spotlight Casts an elliptical beam of light. The line in the preview window defines the light direction and angle, and
the handles define the edges of the ellipse.
Adjust an Omni light
1 Choose Filter > Render > Lighting Effects.
2 For Light Type, choose Omni.
3 Adjust the light:
• To move the light, drag the center circle.
• To increase or decrease the size of the light (like a light moving closer or farther away), drag one of the handles
defining the edges of the effect.
Adjust directional light using the preview window
1 Choose Filter > Render > Lighting Effects.
2 For Light Type, choose Directional.
3 Adjust the light:
• To move the light, drag the center circle.
• To change the direction of the light, drag the handle at the end of the line to rotate the light’s angle. Ctrl-drag
(Windows) or Command-drag (Mac
OS) to keep the light’s height (line length) constant.
• To change the height of the light, drag the handle at the end of the line. Shorten the line for a bright light, and
lengthen it for a less intense one. A very short line produces pure white light; a very long one, no light. Shift-drag
to keep the angle constant and change the height of the light (line length).
Adjust the spotlight using the preview window
1 Choose Filter > Render > Lighting Effects.
2 For Light Type, choose Spotlight.
3 Adjust the light:
• To move the light, drag the center circle.
