Winter Jasmine - Jasminum Nudiflorum in reflected ultraviolet photography and simulated bee and butterfly vision VI

Today in 2023 shots of a beautiful winter flower, a Winter Jasmine - Jasminum nudiflorum 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 propriatary XBV filters. All shots were done at f11. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash.

This flower shows a very prominent and strong UV reflection around 365nm on its petals, but its center is UV-dark, and all this gets nicely visible, also in simulated bee and butterfly vision.
Stay tuned, more will follow on that fascinating subject...

I have previously written about this flower HERE
