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...

False Strawberry - Waldsteinia geoides in reflected ultraviolet photography, simulated bee and butterfly vision

Today shots of a spring flower, a False Strawberry - Waldsteinia geoides 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 Waldsteinia flower has a specific UV pattern, its petals are bright in UV around 365nm, but anthers and stamen are UV dark and this gets quite nicely visible.


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