 | | Sylvanshine, the striking phenomenon, depends upon a bright artificial light source and is seen best on a clear, dark night when the light is shone on (a few species of) dew-covered trees. |
 | | The heiligenschein appears as a bright aura around the head of the observer’s (and only the observer’s) shadow, while the sylvanshine is a bright region spread over the whole tree, but is only seen by the person holding the light. |
 | | To add to the confusion, there is another mechanism which also produces a bright region around the head of the observer’s shadow which does not depend upon dew and has gained the name, heiligenschein. |
