Today shots of two species of a decorative summer flower Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as in simulated butterfly and bee vision using my proprietary XBV filters. Lens was my ZEISS 62mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych (left to right): Human vison, reflected UV, simulated bee vision:
This attractive flower shows its very prominent UV bullseye pattern, its petals have an UV dark bottom and very UV bright tips (around 365nm), invisible to us humans, and all this gets nicely visible.
I have previously written about this flower HERE
Stay tuned, more will follow on that fascinating subject...
