Using the Dodge and Burn Tools

You can also use the Dodge and Burn tools to lighten or darken specific areas of an image. If you wanted to lighten the shadow areas of an image, you would use the Dodge tool, and conversely, if you wanted to darken the highlight areas of an image, you would select the Burn tool. While there are other ways to control the highlights and shadows of an image, such as the Levels adjustment, the Dodge and Burn tools are controlled by using a brush and dragging in the image. That kind of control gives you the option to choose exactly what you want to modify.

Use the Dodge and Burn Tools

Select the

Dodge or

Burn tool on the toolbox.

Select a brush tip, and then select brush options on the Options bar.

Click the

Range list arrow on the Options bar, and then select from the following options:

Midtones. Changes the middle range of grays.
Shadows. Changes the dark areas.
Highlights. Changes the light areas.

Specify the Exposure value for the stroke.

To use the brush as an airbrush, click the

Airbrush button. Alternately, select the Airbrush option in the Brushes palette.

Drag over the part of the image you want to lighten or darken.

Did You Know?

The Sponge tool does not lighten or darken an image. It saturates or desaturates color values as you drag over portions of the image. Since over or under exposed images have a tendency to lose some tonal values and appear flat, you can use the Sponge tool (with Saturate) to return some of the color values back to the image.
