Pasque Flower - Pulsatilla vulgaris in reflected ultraviolet photography, simulated bee and butterfly vision

Today about an early spring flower, a Pasque Flower (Pulsatilla vulgaris) 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. I have already written about that flower before.

This Pulsatilla flower has a quite visible UV pattern, its center is UV dark and this gets quite nicely visible.

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