Abstract
Some embodiments provide a method that provides a graphical user interface (GUI) for color balancing an image. The method provides a display area for displaying the image. The method provides several color balance modes. The method provides a user interface (UI) control associated with a color balance mode in the several color balance modes. The UI control performs a color balance operation on the image by (1) identifying a color cast in the image and (2) modifying pixels in the image based on the pixels' luminance values in order to reduce the color cast in the image.
