Lamp Coronae, Rays & Trees, Finland by Jari Luomanen (more of his images) January 8, 2009. ©Jari Luomanen, shown with permission.

Not a sunlit forest glade but an icy night scene with rays from a halogen lamp sliced by boughs and pine needles then diffracted by nearby fog droplets to produce a corona.

The night lamp was in use to light ice-halos but equally well generates other optical effects.
