Today also about an early spring flower, I have written about before HERE, a Dwarf Tulip (Tulipa pulchella violacea) 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 UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at f8.

This dwarf tulip has a quite visible UV pattern, its center is UV bright, surrounded by long wave UV reflecting tips and all this gets quite nicely visible.
Stay tuned, more will follow on that fascinating subject...
