Treasury flower - Gazania rigens in reflected ultraviolet photography and simulated bee and butterfly vision XIV

Today shots of a current, long blooming spring flower, an all orange variant of a Treasury flower - Gazania rigens in reflected ultraviolet photography and simulated bee and butterfly vision. All shots were done at f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV filters for simulated bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight and background was a bright one.

This Gazania's outer petals reflect strongly UV around 365nm, and there are also highly UV reflecting marks inside around a dark UV center, all invisible to us humans, but all this gets nicely visible, also in simulated bee and butterfly vision.

I have written about Gazania previously HERE
 
Stay tuned, more will follow on that fascinating subject...
