PhotoTune 2.2 from onOne Software is a Photoshop plug-in that features the color correction tools previously known as 20/20 Color MD 2.0 and SkinTune 2.0 which were developed by PhotoTune Software.
After acquiring PhotoTune, onOne has renamed 20/20 Color MD as ColorTune. onOne says ColorTune works like an eye exam to figure out precisely what is wrong with a digital image and how to fix it. During each step of the patented Color Wizard process, users are presented two side-by-side preview images that have been altered in different ways. Users simply click on the best looking image between each pair. The entire six-step process only takes about 15 seconds.
SkinTune, on the other hand, is used to properly correct skin color for accurate skin tone color variations. The technology took more than two years to develop and entailed the collection of thousands of skin tone image samples from around the world.
To use the SkinTune technology, a user just opens an image in Photoshop and select PhotoTune 2.2 – SkinTune from the Filter menu. After two clicks of the mouse, SkinTune instantly finds the nearest acceptable skin color from the selected library, and automatically corrects the image.
