1. An image processing method comprising: receiving an image that has been adjusted based on a first image processing operation; identifying a first set of parameters that quantify a first set of adjustments to the image based on the first image processing operation; computing a second set of parameters that quantify a desired second set of adjustments to the image based on a second image processing operation; comparing the first and second sets of parameters to produce a third set of parameters that expresses the difference between the first and second sets of adjustments; based on the third set of parameters, performing a third image processing operation on the image to produce an adjusted image.
