Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography and simulated bee and butterfly vision XVI

Today in 2021 shots of a human bread beautiful 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 and butterfly vision using my XBV filters. All shots were done at f8. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was my UV enhanced studio flash.

This flower shows a very prominent UV bullseye pattern, as its petal tips are very UV bright (around 365nm) and its center is very UV dark, and all this gets nicely visible, also in simulated bee and butterfly vision.

I have previously written about that flower HERE
 
Stay tuned, more will follow on that fascinating subject...
