Applying Glass Distortion

The Glass Distortion effect creates the kind of distortions you would see if you were

looking at your image through a sheet of glass. You can make your image appear as if

it is behind the pebble glass of a shower door, or you can distort your image beyond

recognition.

Glass Distortion works by relocating the pixels of the image based on a displacement

map. The map is created by combining displacement information from a source with a

preset map type.

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.
