1. An apparatus comprising:
at least one memory configured to store images; and
at least one processor configured to:
receive an input image;
partition a human mask in the input image using a segmentation algorithm;
generate a skin map based on identifying skin in the input image using the human mask;
determine a target scale for brightening based on the skin map, wherein the target scale is limited to a maximum facial brightness based on a contrast exceeding a contrast threshold; and
process an output image with brightening applied using the target scale with the skin map.
