Today about another early spring flower, Dandelion - Taraxacum officinale 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 Dandelion flower has quite a prominent UV pattern, its petals are UV bright around 365nm, its center is UV dark, especially the anthers, and this gets quite nicely visible.
Stay tuned, more will follow on that fascinating subject...
