Today shots of a decorative flower of the Apiaceae family, Italian eryngo - Eryngium amethystinum in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f5.6 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Simulated bee vision:
Quadriptych of human vision, UV, simulated butterfly and bee vision (left to right, top to bottom):
This pretty blue flower has a specific UV pattern, its little individual flower petals are UV bright around 385nm, whereas the flower center is quite UV dark, and all this gets nicely visible, also in simulated bee and butterfly vision.
I have written about that flower before HERE
Stay tuned, more will follow on that fascinating subject...
