1. A method comprising:
identifying a plurality of image pairs from a set of images, each image pair comprising a first image selected from the set of images and a second image selected from the set of images that satisfies image registration criteria with the first image;
determining, separately for each of the image pairs, a normalized camera response function for each of the images in the image pair;
generating an optimized normalized camera response function for each image of the set of images by optimizing the normalized camera response functions determined for two or more image pairs that include the image; and
applying, for each image in the set of images, the optimized normalized camera response function.
