5. To set light properties, drag the corresponding slider for the following options:
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).
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.
Increases (positive values) or decreases (negative values) light. A value of 0 has no effect.
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:
Shines light in all directions from directly above the image—like a light bulb over a piece of paper.
Shines light from far away so that the light angle doesn’t change—like the sun.
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.
