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

Today shots of a decorative flower out of a flower meadow of the same type, Orange coneflower - Rudbeckia fulgida var deamii in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

This attractive flower has a specific UV pattern, its petals have a UV dark bullseye pattern invisible to us humans and the flower center is quite UV dark, and all this gets nicely visible.

There is more about that flower meadow HERE

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