Anemone narcissiflora - Cerco 94mm Quartz Fluorite lens for reflected ultraviolet photography

Today about some early spring flowers, here Anemone narcissiflora (most likely, but looks like a white variant of Liverwort "Anemone hepatica") in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6. So, on to the results now...

Quadtryptich of the above:

This Anemone has only a very slight UV pattern, its center is UV dark and this gets nicely visible.

Stay tuned, more will follow on that fascinating subject...
