Abstract
A digital imaging tool and a method for enhancing, or adjusting, a saturation contrast of a digital image is provided. The digital imaging tool may convert an original color space of a digital image to a second color space having a saturation channel. The digital imaging tool may define a function based, at least partially, on one or more user-provided parameters. Saturation values of pixels of the digital image, in the second color space, may be adjusted, or enhanced, by applying each of the saturation values to the defined function to produce corresponding enhanced saturation values. The second color space then may be converted back to the original color space and a saturation-enhanced version of the digital image may be presented and/or saved.
