Saturate or desaturate areas of your image with the Sponge tool
Use the Sponge tool to saturate or desaturate your images with Photoshop on the iPad
The Sponge tool, a cool saturation tool, is now available in Photoshop on the iPad.
With brush settings like Flow, Hardness, Angle, and Roundness, you can saturate or desaturate any area of your image and create interesting effects.
Pro tip: This tool is best used to achieve subtle saturation effects in your image or creative design.
Of note is the Vibrance setting, where you can toggle between the Vibrance and Saturation dialers which accomplish different things.
With Saturation, you can take all the colors on a layer of an image and make them more saturated overall.
But with Vibrance, you can take specific areas of an image not overly saturated and turn up the saturation, without making the colors appear ‘excessive’.
Put simply, you can dial down (or up!) the richness and intensity of colors in your image using these settings.
