Alters color saturation, or contrast in Grayscale mode

The Sponge tool is a retouching tool used to alter the saturation of a portion of an image. It is reminiscent of the sponges used by watercolor artists to soften (or even remove) a color that has already been lain on the canvas.

The Sponge tool works in two modes:
Desaturate
Color values are brought towards a neutral gray of similar lightness.
Saturate
Color values are made more vibrant.
RGB and CMYK color values are compared to their closest HSL equivalent. Lab color values are simply manipulated along their a and b axes.
Newer versions of Photoshop have the "Vibrance" option, which reduces clipping to primary colors (red, yellow, green, cyan, blue, magenta) or grays. The effect of the tool is lessened for color values already close to these colors.



How to use Sponge Tool.?

  • Launch Adobe Photoshop and open an image file.
  • Click on the sponge tool in the vertical toolbar on the left hand side of your workspace. The sponge tool icon looks like a tiny sponge and shares space with the burn and dodge tools. Some people think locating the sponge tool is the hardest part of using it. Depending on your toolbar setup, you can find this tool roughly midway down the toolbar. It may be hiding behind the hand icon of the burn tool. Put your cursor over the tool, and the tools sharing space pop out to the right. Then you can select the proper tool.
  • Decide if you want to make your color area more or less intense. If you want more color intensity, select "Saturate" from the control bar at the top of your screen. If you want less intensity, click "Desaturate" instead. 
  • Select a brush size and specify a flow for the tool. 
  • Move the sponge tool over the Photoshop image and watch as the color changes. This can be a particularly helpful technique to bring out facial tones in an overexposed photo, but the possibilities are endless.
  • Check your image to see the color change in effect. If you want to reverse the look, check the opposite command from the control panel. For example, if you got the image a little too saturated, choose "Desaturate" and brush over that section again.
