Yellow Flax - Linum flavum in reflected ultraviolet photography and simulated bee vision

Today shots of a decorative yellow flower, Yellow Flax - Linum flavum 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.

This flower has a specific UV pattern, its petals are UV reflective around 365nm and its center is UV dark forming an UV bullseye pattern, and all this gets nicely visible.


Stay tuned, more will follow on that fascinating subject...
