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.

Quadtriptych of some of the above:
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...
