Heiligenschein

Heiligenschein (German for "aureole", literary "holy light") is an optical phenomenon which creates a bright spot around the shadow of the viewer's head. It is created when the surface on which the shadow falls has special optical characteristics. Dewy grass is known to exhibit these characteristics, and create a Heiligenschein. Nearly spherical dew droplets act as lenses to focus the light on the surface beneath them. Some of this light 'backscatters' in the direction of the sunlight as it passes back through the dew droplet. This makes the antisolar point appear the brightest. Skydivers also regularly report this phenomenon surrounding their shadow when cast onto the top surface of an approaching cloud.
