Mexican Zinnia - Zinnia haageana in reflected ultraviolet photography VIII

Today different shots of very decorative flowers, various types of Zinnia haageana - Mexican Zinnia in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U and a UV/IR Cut filter for the visible light shots. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f8.

All diptych images show left results using UV/Cut filter for the visible shots and right using the Baader-U filter (approx. 320-395nm, peak approx. 350nm) for the reflected UV shots.

Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark on 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 side-a-side presentation.

I have written previously about these flowers HERE.

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