When the source of lighting in a picture comes directly from above; the opposite of underlighting.
Because lighting generally comes from above in most pictures this tag should only be used when the shading is emphasized, for example by making front-facing surfaces such as the face and torso shaded when normally they wouldn't be shaded in a picture.
Examples
Non-examples
there's an artificial light (a spotlight) but no shading present
light coming from the sun above the character, but shading isn't emphasized
