Triptych of the above images:  


This attractive flower has a very specific UV pattern, its petals are bright on the petal tips (reflecting around 365nm), have a UV dark bullseye pattern invisible to us humans and also the flower center is quite UV dark, and all this gets nicely visible.

I have previously written about that flower HERE.

Freudenberg Villa at Hermannshof Park in reflected ultraviolet photography and simulated bee vision

Today shots of the former Freudenberg Villa (visible in the background castle Wachenburg), today owned and used as a meeting location by German company Freudenberg, located in the beautiful public Hermannshof Park jointly owned and operated by teh City of Weinheim and the comapany Freudenberg where I like to take flower pictures as there are about 2500 flower species to be found. Shots were done in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was a 55mm Dialyte lens. Light source was sunlight. All shots were done at about f8.
