SkinTune plugin
From RobGalbraith comes the news of a new Photoshop plug-in for Mac or Windows that takes a very different and innovative approach to the problem of colour correction in images. Rather than a complicated process of colour adjustment based on hues, colour-channels etc, the aptly named SkinTune from the company PhotoTune attempts to achieve natural-looking colour correction based on skin tones. They collected thousands of sample images of all different races from around the world, took precise spectrophotometer measurements, and then compiled a database which is the basis of the plug-in. Basically you choose the likely race of the subject and then have options for fine-tuning. Technical notes on the process can be found here and demo versions can be downloaded here.
