Those multispectral images of mine where shot in my studio and outside with my "work horse" UV-Nikkor f4.5/105mm quartz fluorite lens using the Baader UV/IR Cut filter and my proprietary XBV filters for simulated bee vision. Light source in studio used was a Xenon flash modified for high UV output and sunlight outside.

All these flowers have very specific UV patterns; the outer part of their petals are UV reflective around 360nm, but their inner parts show a UV-dark area which gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
