Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography XXVIII

Today shots of very decorative summer flowers, Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was my ZEISS 62mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Mexican Zinnia flowers have very specific UV patterns. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (around 360nm outer tip, 350nm middle tip, 345nm border to dark), reaching deeper into UV as any other flower I know of, and all this gets nicely visible.

I have previously written about those Zinnias HERE

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