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.

Human vision (VIS):

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
Stay tuned, more will follow on that fascinating subject...
