1. A method of processing a digital image using face detection, the method comprising:

  • identifying a first group of pixels that correspond to a first face region within a digital image;

    determining one or more first initial color values for pixels in the first group of pixels;

    based on the one or more first initial color values for the pixels in the first group of pixels, determining a first skin tone for the first face region;

    identifying a second group of pixels that correspond to a second face region within the digital image;

    determining one or more second initial color values for pixels in the second group of pixels;

    based on the one or more second initial color values for the pixels in the second group of pixels, determining a second skin tone for the second face region;

    determining whether the first skin tone is lighter than the second skin tone; and

    in response to determining that the first skin tone is lighter than the second skin tone;

    based on, at least in part, the first skin tone and the second skin tone, determining an initial fill-flash and applying the initial fill-flash to the first face region;

    based on, at least in part, the first skin tone and the second skin tone, increasing the fill-flash and applying the increased fill-flash to the second face region.
