Continuing on the favorite topic of pollen coronas, here are two rather painstakenly constructed images of pine pollen corona.
The white dots are wind dispersing seeds, probably of some willow species. They are more abundant in the lower image, which was taken in town. The upper image was shot in the midst of pine heath, with correspondingly less white fluffs in the air.
On 13. June 2006 in Eastern Finland. Larger sized versions are here.
