Corel Painter Help | Adjusting light properties

Adjusting light properties

You can adjust light properties such as brightness, distance, elevation, and color. Light properties have a cumulative effect. For example, if you turn up a light’s brightness, you might need to adjust exposure.

To adjust the light properties

1 To apply the effect to:

• The canvas — Click the Canvas in the Layers panel.

• A selection — Click a selection tool from the toolbox, and drag in the document window to select an area.

• A layer — Click a layer in the Layers panel.

2 Choose Effects

Surface Control

Apply Lighting.

3 In the preview window, click an indicator to select it.

4 In the Directional Lighting area, move any of the following sliders:

• Brightness — controls the light intensity

• Distance — controls how far the light is from the image. If you move the light source closer, you can compensate for the increased light by adjusting the Exposure slider.

• Elevation — sets the light’s angle in relation to the canvas. At 90°, the light is shining straight down, and at 1°, it’s nearly horizontal.

• Spread — sets the angle of the light cone

To change the light color, click the Color chip, and choose a color.

5 In the Ambient Lighting area, move any of the following sliders:

• Exposure — controls the image’s brightness, as in photography. Moving the slider to the left decreases exposure and darkens the image; moving it to the right increases exposure and lightens the image.

• Ambient — controls the surrounding light in an image. If you have no light indicators in the preview window, the ambient lighting controls the overall lightness of the image. Moving the slider to the left darkens the overall lighting; moving it to the right increases the light.

To change the color of the ambient light, click the Color chip, and choose a color.
