Rock tulip - Tulipa saxatilis in reflected ultraviolet photography, simulated bee and butterfly vision III

Today some shots of an early spring flower I have written about before, a Rock tulip - (Tulipa saxatilis "Lilac Wonder") (often wrongly labeled T. bakeri) 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 about f8.

This rock tulip has a not so strongly visible UV pattern, its petals are UV bright, and this gets quite nicely visible in these close-ups.

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