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

Today shots of a long blooming spring flower, a pink variant of a Treasury flower - Gazania rigens in reflected ultraviolet photography and simulated bee 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 filter for simulated bee vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight, background was gray.

This Gazanias' outer petals massively reflect UV around 375nm, contrasting strongly against its dark UV center, all invisible to us humans, but all this gets nicely visible, in simulated bee vision also.

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