Creeping Cinquefoil - Potentilla reptans flower in reflected UV ultraviolet photography and simulated bee vision II

Today about another early spring flower which I have shown here before in close-up, Creeping Cinquefoil (Potentilla reptans) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

This Potentilla flower has quite a prominent UV pattern, its center is UV dark and this gets quite nicely visible, even in this "meadown" overview shot.

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