Today more shots of a different type of that decorative flower, Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6. I have previously written about those Zinnias HERE.

Triptych of the above images:
Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark in the middle and bottom, but their petal tips are very UV bright, reaching much deeper into UV as any other flower I know (< 345nm), and all this gets nicely visible in this presentation.
Stay tuned, more will follow on that fascinating subject...
