Today shots of a decorative summer flower Missouri Coneflower - Rudbeckia missouriensis 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 filter. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was sunlight. All shots were done at f8.

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.
Stay tuned, more will follow on that fascinating subject...
