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

Today shots of a decorative summer flower which just started to bloom in my fav pak, 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 CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

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.

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

Today now a summary of shots of some specimens 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.

Sequence of quadriptychs is (left to right, top to bottom): Human vision, UV, simulated butterfly vision, simulated bee vision:
 

 

 

 

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.

Hawksbeard - Crepis in deep reflected ultraviolet photography, simulated butterfly and bee vision VI

Today shots of even another species of Hawksbeard - Crepis sp. in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f8.
