Today different shots of a decorative flower, a Zinnia haageana - Mexican Zinnia in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U and Jupiter-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a Hamamatsu 50mm lens. Light source was Xenon flash. All shots were done at about f8.

Quadriptych of some of the above:
Mexican Zinnia flowers have a very specific UV pattern, its petals are very UV dark on the middle and bottom, but its petal tips are very UV bright, reaching much deeper into UV as any other flower I know (<345nm), and all this gets nicely visible.
I have written previously about these flowers HERE.
Stay tuned, more will follow on that fascinating subject...
