Using Image Luminance to Create Texture

When you create a texture using the Image Luminance method, the current image's luminance, or lightness, determines where surface texture is added. Light parts of the image create dents; darker parts create raised areas. The overall effect gives an embossed look to the edges of the image.

Before (left) and after(right) adding texture based on Image Luminance.

To create surface texture by using Image Luminance

1 Select a layer or area of the canvas.

If you want to apply the effect to the entire image, do not make a selection.

2 Choose Effects menu > Surface Control > Apply Surface Texture.

3 In the Apply Surface Texture dialog box, choose Image Luminance from the Using pop-up menu.

If you want to apply an inverted texture, enable the Inverted check box.

4 Adjust the Softness slider to control the amount of distortion created by the texture.

Increasing softness creates more intermediate steps, which produces a smoother distortion.

5 Adjust the Appearance of Depth sliders.

Refer to "Setting Appearance of Depth Properties" on page 292 for more information.

6 Adjust the Light Controls sliders.

For more information, refer to "Applying Lighting to a Texture" on page 303.
