Abstract
Methods and apparatus, including computer program products, for performing color correction. One product can receive a digital image that includes a region depicting human skin; obtain a skin color value based on a sample; receive a skin parameter value that is a tan or a blush value; use the skin color value and the skin parameter value to determine an estimated ambient lighting condition of the image; and determine a color correction based on the estimated lighting condition and a target lighting condition. Another product can use the skin color value to determine an estimated color temperature of the image and an estimated tint shift of the image, and can determine a color correction based on the estimated lighting condition and a target lighting condition and the estimated tint shift. Another product can use the skin color value and the skin parameter value to determine an estimated camera color setting.
