Today shots of a spring flower Apache beggarticks - Bidens ferulifolia 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 X80QF quartz fluorite lens. Light source was sun. All shots were done at about f8.

Bidens has a strong visible UV pattern, its petal tips are UV bright around 365nm, its center is quite UV dark, so this gets quite nicely visible.
Stay tuned, more will follow on that fascinating subject...
