Today shots of an early spring flower, Star-of-Bethlehem - Ornithogalum umbellatum. in reflected ultraviolet photography and simulated bee vision. All shots were done at about f5.6 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV6 filter for simulated bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight.

Triptych of human vision, UV and simulated bee vision (left to right):
This Star-of-Bethlehem flower has a less prominent UV pattern, its petals however are very UV bright around 370nm, its center is a bit darker in UV and shows a shifted reflection to about 380nm and all this gets nicely visible, also in simulated bee vision.
Stay tuned, more will follow on that fascinating subject...
