Black-Eyed-Susan - Rudbeckia fulgida in reflected ultraviolet photography and simulated bee and butterfly vision VI

Today in 2021 shots of a beautiful flower, originating from the USA Prairie, a Black-eyed Susan - Rudbeckia fulgida in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as in simulated bee and butterfly vision using my XBV filters. All shots were done at f8. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight (shade).

Quadriptych of human vision, ultraviolet, simulated butterfly and bee vision (left to right, top to bottom):
 

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

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

Black-Eyed-Susan - Rudbeckia fulgida: HDTV video in human vision and simulated bee vision

Today video shots of a famous "UV-flower" Black-Eyed-Susan - Rudbeckia fulgida in human and simulated bee vision. All shots were done at f5.6 in visual  videography and using my XBV filter for simulated bee vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Simulated bee vision (BV):
 

And now VIS and BV HDTV videos shot in parallel of a selected flower with pollinating bees:
Black-Eyed-Susans have a distinct UV reflection "bulls eye" pattern, its petals have a quite UV dark center (visible as green in simulated bee vision) and the outside part is quite UV bright around 365nm (visible as bright yellow in sim. bee vision). All this gets nicely visible, also in simulated bee vision as well as in the HDTV videos.

I have written about that flower before HERE
