Rockfoil - Saxifraga in reflected ultraviolet photography and simulated bee and butterfly vision I

Today shots of some beautiful little whitish flowers Saxifraga - Rockfoil in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as in simulated bee and butterfly vision using my XBV filters. All shots were done at f11. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

This flower shows no very prominent UV pattern, its petals somewhat transparently shine in UV (around 385nm), and all this gets nicely visible, also in simulated bee and butterfly vision.
 
Stay tuned, more will follow on that fascinating subject...
