The Sponge Tool

The Sponge tool breaks with the nice photography metaphor we've been using to this point. To my knowledge, photographers don't sit in the darkroom and dab sponges on their photos. They do however, use them in Photoshop.

Keep the tools moving

In the darkroom, photographers dodge and burn using a constant circular motion, keeping the tool moving the entire time. This is to avoid any sharp edges around the area being modified. The same is true for the Dodge and Burn tool in Photoshop. Use a feathered brush, a low

exposure, and build up the effect with a repetitive circular motion. The Sponge tool controls the saturation in a color image and the contrast in a black-and-white image. Saturation refers to the intensity and purity of the color in an image. Scenes such as sunsets, bright summer days, and night photography tend to be overly saturated. When you modify saturation, you need to be careful, in that too much saturation can make an image look unnatural. In select spots, or for more of a graphic effect, saturation can be a powerful tool.

In the Sponge tool Options palette, the tonal range pop-up menu has been replaced by the Saturate/Desaturate pop-up menu (Figure 15.5). Select one or the other to increase or decrease the color intensity. Although the name on the other control has been changed from Exposure to Opacity, the result is still the same; increase the value and the effect is applied faster.

Using the Saturation tool

1. Select the Sponge tool from the Dodge/Burn/Sponge pop-out menu, and double-click the Sponge tool to launch the Options palette.

2. Select Desaturate from the Options palette pop-up menu and set the Opacity to 20.

3. With an appropriate-sized brush selected, brush in circles over the midtone areas in the image to soften and tone down the color values (Figure 15.6).
