Today shots of a decorative summer flower which just started to bloom in my fav pak, 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 CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

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...
