Black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography and simulated butterfly and bee vision IX

Today more studio shots of a flower originating from the USA Prairie, a Black-eyed Susan - Rudbeckia hirta 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 newer, enhanced XBV filters. All shots were done at f8. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash, background was a dark gray. [These shots were done with a new camera system and are available on request in very high resolution (40 and 60 Mp)].

This flower shows a very prominent UV bullseye pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is very UV dark, and all this gets nicely visible, also in simulated butterfly and bee vision.

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