1. A method, comprising: receiving an input image comprising pixels within a region that is brightly illuminated; computing, by a processor rendering a phenomenological model, an afterimage corresponding to the region, wherein first colors of pixels in the afterimage correspond to an intensity of the brightly illuminated region; accumulating the afterimage into an output image, wherein the afterimage brightens the pixels within the region of the output image; displaying the output image; computing, by the processor rendering the phenomenological model, a second afterimage, wherein at least a portion of second colors of pixels in the second afterimage are different than the first colors; accumulating the second afterimage into a second output image; and displaying the second output image.
