Rhododendron ponticum in reflected ultraviolet photography, simulated bee vision

Today shots of a spring flower, a Rhododendron ponticum 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 Rhododendron flower has no specific UV pattern, rather similar to the visible image, but its petals are bright in UV around 380nm, and anthers and stamen are UV dark and this gets nicely visible.


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

[UV] 340nm Jupiter-U filter for short wave reflected UV (2)

Again more about that new Jupiter-U filter of mine. Shots taken today at the wonderfully blossoming Hermannshof Park, Weinheim, Germany.

That new filter renders quite differently; nicely golden actually.


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