Heiligenschein Heiligenschein 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. Both dry dusty surfaces and Dewy grass are known to exhibit these characteristics. 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. The glory creates a similar halo effect by a different mechanism.
