Field Forget-me-not - Myosotis arvensis in reflected ultraviolet photography, simulated bee vision

Today shots of a spring flower (with yellow Waldsteinia in the background), a Field Forget-me-not - Myosotis arvensis in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

This Myosotis flower has a quite specific UV pattern, its petals are bright in UV around 385nm, but its center is quite darker and this gets nicely visible.


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