Snakeshead - Arum maculatum in reflected ultraviolet photography and simulated bee vision

Today shots of the very decorative late summer berries of the Snakeshead - Arum maculatum 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 UV-Nikkor 105mm quartz flourite lens. Light source was sunlight. All shots were done at f8.

This attractive berries shows no prominent UV pattern, but a metallic like shine, peaking at around 365nm, invisible to us humans, and all this gets nicely visible.

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

Missouri Coneflower - Rudbeckia missouriensis in reflected ultraviolet photography, simulated butterfly and bee vision III

Today more shots of a group of decorative summer flowers Missouri Coneflower - Rudbeckia missouriensis 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 filter.

This attractive flower shows its very prominent UV bullseye pattern, its petals have an UV dark bottom and very UV bright tips (around 365nm), invisible to us humans, and all this gets nicely visible in this group shot.

I have written about this flower previously HERE

Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography, simulated butterfly and bee vision XI

Today shots of two species of a decorative summer flower Orange coneflower - Rudbeckia fulgida 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 ZEISS UV-Planar f2/62mm 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 III

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 ZEISS UV-Planr f2/62mm 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 that gets nicely visible here, also in simulated bee vision.

Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography XXIX

Today more 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 UV-Planar f2/62mm 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
