Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography, simulated butterfly and bee vision XIII

Today about composite shot of a decorative summer flower Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was my CERCO 94mm quartz flourite lens. Light source was a modified for high UV output Xenon flash. 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, but very visible to bees and butterflies, and all this gets nicely visible.

I have previously written about this flower HERE

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