Relight

Relight is a fast and easy to use photo color correction tool. It can be used to quickly: Fix photos that are too red, too blue, or have been tinted some other color; Fix faded, overexposed, and underexposed images; Restore old faded photographs to their former glory; Perform other creative color transformations.

Key Features: Has a simple, easy to use interface (doesn't have a myriad of complex functions cluttering up the GUI like heavy-weight image processing and photo manipulation suites do); Real-time (instant) feedback and response for easy adjustment; Color transformation engine maps colors in the image to their correct colors; Correct one photo using the colors extracted from another. At Relight's core is a color transformation engine. The user indicates what color certain parts of the image should be, and the matching color correction transformation (or creative transformation) is calculated by Relight. You could, for example, correct an image by marking a person's face as being skin color.
