Here today shots of the well known Creeping Cinquefoil - Potentilla reptans early spring flower. Shots were done aside from visible photography in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens used my X80QF f3.2 / 80mm Quartz Fluorite lens. Light source was sun. All shots were done at approx. f8.

Triptych of the above images:
This Potentilla flower has a well known bulls-eye UV pattern, its center is UV dark, whereas its petals strongly reflect around 365nm. The X80QF quartz fluorite lens is reproducing this quite well and all that gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
