Add Lighting Effects
You can use up to five lights to introduce
creative effects. You can control such lighting properties as lighting
type, direction, intensity, color, lighting center, and lighting
spread. There is also a Bump Layer control for using textures or
patterns from other footage to produce special effects such as a
3D‑like surface effect. Note: All Lighting Effects properties except
Bump Layer can be animated using keyframes.
You can
directly manipulate the Lighting Effects properties in the Program Monitor.
Click the Transform icon next
to Lighting Effects in the Effect Controls panel to display the
adjustment handles and Center circle.

- In the Effects panel, expand the Video Effects
bin, expand the Adjust bin, and then drag the Lighting Effects onto
a clip in a Timeline panel.
 If a clip is already selected in a Timeline
panel, you can drag the Lighting Effects directly to the Video Effects
section of the Effect Controls panel.
- In the Effect Controls panel, click the triangle to expand
the Lighting Effects.
- Click the triangle to expand Light 1.
- Choose a light type from the pop‑up menu to specify the
light source:
- None
- Turns off a light.
- Directional
- Shines light from far away so that the light angle doesn’t
change—like the sun.
- Omni
- 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.
- 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.
- (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.
- 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.
- 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.
- Exposure
- Increases (positive values) or decreases (negative values)
the light’s brightness. A value of 0 is the default brightness of
the light.
- (Optional) Repeat steps 3 ‑ 7 to add more lights (Light
2 ‑ Light 5).
- (Optional) If you added a clip to use as a bump layer
(Lighting Effects texture), choose the track containing the bump
layer clip from the Bump Layer pop‑up menu. Use the controls to
adjust the properties for the bump layer.
