Aureola crown, modified by an equally simple idea of the emanation of light from the head of a superior being, or by the meteorological phenomenon of a halo. The probability is that all later associations with the symbol refer back to an early astrological origin (compare Mithras), the person so glorified being identified with the sun and represented in the sun's image; so the aureole is the "Hvareno" of Mazdaism.

Aureole effect camera at arm's length, the aureole effect appearing in the picture will be seen radiating from the shadow of the camera, although the photographer would still see it around their head's shadow while taking the picture. This happens because the aureole effect always appears directly opposite the sun, centered at the antisolar point. The antisolar point itself is located within the shadow of the viewer, whatever this is: the eyes of the viewer or the camera's lens. As a matter of fact, when aureole effects are photographed from a plane, it is possible to tell where the photographer was seated.
