Mexican Zinnia - Zinnia haagenea in (deep) reflected ultraviolet photography XXVII

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 as well as a 340nm short pass filter for deep(er) UV photography. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych (left to right): Human vision, reflected UV (320-395nm), deep reflected UV (320-340nm):
 

Mexican Zinnia flowers have very specific UV patterns which reach quite deep into UV. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (here around 370nm outer tip, 365nm middle tip). Deeper UV photography reveals, that the outer tip part reaches even deeper into UV, deeper 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...

Mexican Zinnia flowers have very specific UV patterns and here, although their visible representations look very differently, their reflected UV pattern is nearly the same. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (around 370nm outer tip, 365nm middle tip, 350nm border to dark), reaching deeper into UV as any other flower I know of, and all this gets nicely visible.

Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography and simulated butterfly and bee vision XXV

Today more shots of a very decorative summer flower, Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated butterfly and bee vision using my proprietary XBV filters. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Day Lilly - Hemerocallis lilioasphodelus in reflected ultraviolet photography and simulated bee vision II

Today shots of an attractive summer flower, a creamy yellow Day Lilly - Hemerocallis lilioasphodelus in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my proprietary XBV filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Most Hemerocallis have a very prominent "dark throat" UV pattern, and also that gets nicely visible, also in simulated bee vision.

This attractive flower has a specific UV "bulls eye" pattern, its petals and its center are UV dark, invisible to us humans and the flower outer petals are UV bright (around 365nm), and all this gets nicely visible, also in simulated bee vision.

I have previously written about that flower HERE
