Today shots of a flower originating from the USA Prairie, a Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was a modified Xenon flash. All shots were done at f8.

Triptych of the above images:
This flower shows a very prominent UV bullseye pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is very UV dark, and all this gets nicely visible also in simulated bee vision.
I have previously written about that flower HERE.
Stay tuned, more will follow on that fascinating subject...
