Today about another early spring flower, 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.

Triptych of the above:
This Potentilla flower has quite a prominent UV pattern, its center is UV dark and this gets quite nicely visible.
An overview, "meadow" shot may be seen here.
Stay tuned, more will follow on that fascinating subject...
