The Highpass effect introduces stark shifts between brightness levels.

To apply a Highpass effect

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  Esoterica  Highpass.

3 In the Highpass dialog box, choose an aperture option.

4 Move the Amount slider to determine how much to suppress the low-frequency

This value defines a radius, in pixels, around each pixel in the selected image area.

Moving the slider to the left suppresses larger amounts of low-frequency

information. Moving the slider to the right suppresses smaller amounts of

low-frequency information.

Applying the Maze effect

The Maze effect generates an image of a maze. Typically, you’ll create a maze in a new,

blank image. Each maze has one “solution” — that is, an open path from the entrance

to the exit.
