Aureole effect

The aureole effect or water aureole is an optical phenomenon similar to Heiligenschein, creating sparkling light and dark rays radiating from the shadow of the viewer's head.

Suspended particles in the water help make the aureole effect more pronounced.

[1] Although the focused (light) ray cones are actually more or less parallel to each other, the rays from the aureole effect appear to be radiating from the shadow of the viewer’s head due to perspective effects.

Similarly, if a photographer holds their 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.
