Applying Depth of Field

This effect creates a blur similar to the distance from the plane of camera focus in photography. You can specify the radius of the blurring effect in the image.

depth of field

The "M" is a floating shape. The blur on the shadow was created by using Depth of Field.

There are five different methods for applying Depth of Field:

•

Uniform Color — applies the effect uniformly to the image

•

Paper — applies the effect by using the paper texture luminance (brightness) as a mapping model. More of the effect is applied to the dark areas in the paper grain; less of the effect is applied to the light areas. If you want to experiment with the effect, keep the Papers panel open while you apply the effect. This way you can switch to different papers and modify the paper controls.

•

Image Luminance — uses the image’s luminance as the model for the effect. More of the effect is applied to dark areas in the original image; less color is applied to light areas.

•

Original Luminance — uses the luminance of the clone source (or a pattern) as the model for the effect. More of the effect is applied to dark areas in the clone source (or pattern); less color is applied to light areas.

•

Alpha Channel or Layer Mask — sets the values in the channel or layer mask as the model for the effect. More of the effect is applied to dark areas in the layer mask or channel; less color is applied to light areas. You can use this method only if you have a saved alpha channel or a layer mask in your image.

To apply Depth of Field uniformly

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

Focus

Depth of Field.

3 .

Choose Uniform Color from the Using list box.

4 .

Adjust any of the Depth of Field controls. For information, see Depth of Field controls.

To apply Depth of Field by using paper luminance

1 .

Do one of the following:

•

On the Brush tool

property bar, click the Grain flyout button

.

•

Choose Window

Media Panels

Papers to open the Papers panel.

2 .

Click a paper texture swatch in the Paper Textures area.

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.

4 .

Choose Effects

Focus

Depth of Field.

5 .

Choose Paper from the Using list box.

2 .

Choose Effects

Focus

Depth of Field.

3 .

Choose Image Luminance from the Using list box.

Darker regions of the source receive greater blur.

4 .

Adjust any of the Depth of Field controls. For information, see Depth of Field controls.

To apply Depth of Field by using clone or pattern luminance

1 .

Perform a task from the following table.

Do the following

Use a clone source

In the Clone Source panel (Window

Clone Source), choose Embedded Image from the Source list box.

In the Embed Source Image dialog box, do one of the following:

To browse for a file, enable the Browse option.

To clone a currently open document, enable the Current Document option, and choose a document from the list box.

To embed the active texture, enable the Current Texture option.

Choose Window

Media Panels

Patterns, and click a pattern swatch in the Painter Patterns area.

2 .

•

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.

3 .

Choose Effects

Focus

Depth of Field.

4 .

Adjust any of the Depth of Field controls. For information, see Depth of Field controls.

To apply Depth of Field by using layer mask or channel luminance

1 .

Do one of the following:

•

To use a layer mask, choose Window

Layers, and click the layer that contains a layer mask in the Layers panel.

•

To use an alpha channel, choose Window

Channels, and click the alpha channel in the Channels panel.

2 .

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.

3 .

Choose Effects

Focus

Depth of Field.

4 .

Choose Original Luminance from the Using list box.

Darker regions of the source receive greater blur.

5 .

Adjust any of the Depth of Field controls. For information, see Depth of Field controls.

Depth of Field controls

•

Min Size — sets the minimum radius of the blur regions

•

Max Size — sets the maximum radius of the blur regions

The maximum size must be greater than the minimum size.
