Well, spring finally seem to have arrived in Weinheim where I live, so here a few shots of some first spring flowers, like that Bellis perennis - Common Daisy.. 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 was an older f3.2 / 80mm Quartz Fluorite lens. Light source was sun. All shots were done at approx. f8.

Visible light image:
UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
Simulated bee vision image using experimental XBV filter:
Common Daisy has a bulls-eye UV pattern, its center is UV dark, and the petals are UV reflective aroudn 380nm. This older quartz fluorite lens is reproducing this quite well and all that gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
