Choose a light type from the pop-up menu to specify the light source:
N
one
Turns off a light.
Directional
Shines light from far away so that the light angle doesn’t change—like the sun.
O
mni
Shines light in all directions from directly above the image—like a light bulb over a piece of paper.
Spotlight
Casts an elliptical beam of light.
5
To specify a color for the light, do one of the following:
•
Click the color swatch, select a color using the Adobe Color Picker, and then click
OK.
•
Click the Eyedropper icon and then click anywhere on the computer desktop to select a color.
6
(Optional) Click the Transform icon to display the light’s handles and Center circle in the Program Monitor. You
can directly manipulate the position, scale, and rotation of a light by dragging its handles and Center circle
.
Note:
If you have more than one light, Center circles for each light appear in the Program Monitor. Clicking a Center
circle displays the handles for a specific light.
7
In the Effect Controls panel, use the following controls to set the properties for the individual source light:
Center
Moves the light using X and Y coordinate values for the center of the light. You can also position a light by
dragging its Center circle in the Program Monitor.
Major Radius
Adjusts the length of an Omni light or Spotlight. You can also drag one of the handles in the Program
Monitor.
Projected Radius
Adjusts the proximity of a Directional light’s source to the Center circle
.
A
value
of
0
positions
the light at the Center circle and floods the image with light. A value of 100 moves the light source far from the
Center circle, decreasing the light falling on the image. In the Program Monitor, you can also drag the light source
point to adjust its distance from the Center circle.
Minor Radius
Adjusts the width of a Spotlight. Once the light becomes a circle, increasing the Minor Radius also
increases the Major Radius. You can also drag one of the handles in the Program Monitor to adjust this property.
Angle
Changes the direction of a Directional light or Spotlight. Adjust this control by specifying a value in degrees.
You can also move the pointer outside a handle in the Program Monitor until it turns into a double-headed curved
arrow
, and then drag to rotate the light.
Intensity
Controls whether a light is bright or less intense.
Focus
Adjusts the size of the Spotlight’s brightest area.
Important:
The Light Type determines which Lighting Effects properties are available. Make sure to click the
Transform icon to display a light’s handles and Center circle in the Program Monitor.
8
Use the following controls to set the Lighting Effects properties:
Ambient Light Color
Changes the color of the ambient light.
Ambience Intensity
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.
Surface Gloss
Determines how much the surface reflects light (as on the surface of a piece of photographic paper)
from –100 (low reflectance) to 100 (high reflectance).
Surface Material
Determines which is more reflective: the light or the object on which the light is cast. A value of –
100 reflects the light’s color, and a value of 100 reflects the object’s color.
