Today about a fallen to the ground colorful autumn leaf of an American Sweetgum - Liquidambar styraciflua tree in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was sunlight. All shots were done at f8.

Diptych: Human vison (left side), reflected UV (right side):
This amber tree leaf shows fine leaf structures in VIS and reflected UV, but in UV larger dark patches get visible, where this leaf shows damage and decay, and all this gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
