Today shots of a spring flower I have written about before, Marsh marigold (Caltha palustris) 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.

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
Simulated bee vision (UV - VIS) using XBV6 filter:
Triptych of the above:
This Caltha flower has quite a prominent UV pattern, its center is UV dark, as well as some UV dark veins on its petals. The bee vision image additionally reveals some lit up anthers and all this gets quite nicely visible.
Stay tuned, more will follow on that fascinating subject...
