Today shots of a decorative flower, Three-leaved Coneflower - Rudbeckia triloba 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 (In the background are some R.fulgida I have previosly written about). Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych of the above images:
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.
Stay tuned, more will follow on that fascinating subject...
