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.

Quadriptych human vision, UV, sim. butterfly vision, sim. bee vision (left to right, top to bottom):

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...
