Using the Sponge tool (Photoshop)

The Sponge tool subtly changes the color saturation of an area. In Grayscale mode, the tool increases or decreases contrast by moving gray levels away from or toward the middle gray.

To use the Sponge tool:

1. Select the Sponge tool .
2. Choose a brush tip and set brush options in the options bar (see Working with brushes).
3. In the options bar, select the way you want to change the color.
• Saturate to intensify the color's saturation
• Desaturate to dilute the color's saturation
4. Specify the flow for the Sponge tool. (See Specifying opacity, flow, strength, or exposure.)
5. Drag over the part of the image you want to modify.
