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

    detecting a skin tone for the face image by determining one or more color or tonal values, or combinations thereof, for the group of pixels and comparing with one or more default color or tonal values, or combinations thereof; and

    adjusting values of one or more parameters for the group of pixels, including adjusting values of luminance to open up shadows within the face image by selectively applying fill-flash to regions within the face image in an amount based on the detected skin tone.
