Here today shots of the pretty Elephant's ears - Bergenia cordifolia early spring flower. Shots were done aside from visible photography in reflected ultraviolet using Baader-U and the deeper reaching Jupiter-U filter, as well as in simulated bee vision using my XBV6 filter. Lens used was my X80QF f3.2 / 80mm Quartz Fluorite lens. Light source was sun. All shots were done at approx. f8.

Quadriptych of the above images:
This Bergenia flower has no prominent UV pattern, but highly UV reflective petals around 385nm. 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...
