Before (left) and after (right) applying Glass Distortion.

There are five sources of displacement information:

• Paper uses the information in a paper texture to displace pixels. More displacement is applied to light

areas of the texture, and less to dark areas. Paper texture is good for creating the pebbled glass effect.

Unless you want frosted glass, you’ll probably want to increase the scale of the paper.

• 3D Brushstrokes uses the difference in luminance between the brushstrokes applied to the clone and

the current document

• Image Luminance uses the light and dark areas in the current document to determine the intensity of

distortions

• Original Luminance uses the clone source’s luminance. Use a tessellation as the clone source to

produce a bumpy glass effect.

• [Alpha channel] or [Layer mask] uses the luminance of a channel or layer mask. More distortion

appears in the light areas of the channel. You must have a saved alpha channel or layer mask to use this

source.

To create a controlled distortion map, choose an alpha channel or a layer mask as a source. For example,

gradations in the channel lead to a progressive distortion effect. Shapes in the channel produce

distortions with distinct outlines.

To apply glass distortion by using paper luminance

Choose Window Paper Panels Papers.

2 Choose a paper swatch from the Papers library panel.

3 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.

Choose Effects Focus Glass Distortion.
