Today shots of an attractive summer flower, Jerusalem artichoke - Helianthus tuberosus in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my proprietary XBV filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych (left to right): Human vision, reflected UV and simulated bee vision:
This attractive flower has a specific UV "bulls eye" pattern, its petals and its center are UV dark, invisible to us humans and the flower outer petals are UV bright (around 365nm), and all this gets nicely visible, also in simulated bee vision.
I have previously written about that flower HERE
Stay tuned, more will follow on that fascinating subject...
