Flax - Linum angustifolium in reflected ultraviolet photography and simulated bee vision

Today shots of an early spring flower, Flax - Linum angustifolium. in reflected ultraviolet photography and simulated bee vision. All shots were done at about f5.6 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV6 filter for simulated bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight.

Triptych of human vision, UV and simulated bee vision (left to right):

This Flax flower has a less prominent UV pattern, its petals however are quite UV bright around 380nm, its center is dark in UV forming the typical bullseye pattern and there are also UV dark veins visible leading to the UV dark center, where the nectar is and all this gets nicely visible, also in simulated bee vision.

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