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

Today more shots of a cultivar 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 bee and butterfly vision using my XBV filters. All shots were done at f11. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was a modified Xenon flash. This was shot using my previously used modified high resolution camera (40/80Mpix), an Olympus M5 Mk2

This flower shows a very prominent UV bullseye pattern, as its petal tips 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 bee and butterfly vision. I have matched the previously done shooting for comparison reasons.

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

My work on TV, Movie Theaters etc in UV and simulated animal vision

So if you would like to see some of my work on TV or on film (updated 02 2023), here you go ...

Work for NOVA PBS:

They will produce a TV special "Your Brain: Perception Deception" (working title) using my multispectral images of Bidens, Gazania and Rudbeckia in human vision and simulated bee vision. It will air in 2023.

Work for NEBRASCA PUBLIC MEDIA:

Our video "Insecta Spectra" done by Robin Noorda using my multispectral images will be used in an interactive lesson on bees and pollinators. There will be a section describing what bees see as opposed to what a human sees in the environment - particularly flowers. It will air in 2022.

Work for BBC London:

BBC ONE Richard Hammond's Invisible Worlds (HDTV)

BBC TWO The Science of Plants - How to Grow a Planet (HDTV)

BBC Four - Colour: The Spectrum of Science (HDTV)

BBC Science Interview on Bees and their UV Vision (HDTV)

 

Work for Sir David Attenborough:

Kingdom of Plants (HDTV for SKY 3D and IMAX Theaters; in 3D stereoscopic)

Work for Wall to Wall Productions:

Solved: Nature's Strangest Mysteries 

Work for the German TV:

ZDF TerraX "The Magic of Colors" (HDTV)

ZDFZeit about UV Sun protection (HDTV)

Hessischer Rundfunk (hr), production Alles Wissen, Blumen Quiz (2019)

WDR 2 Bienen live ("bees live")

 

 

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

Today detail shots of a cultivar 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 bee vision using my XBV filter. All shots were done at f8. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

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

Today shots of a current, long blooming flower, a yellowish white 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, background was the flower's own foliage.

This Gazania's outer petals reflect strongly UV around 372nm, wheras the inner parts are much darker hence forming UV nectar guides for bees. There are also highly UV reflecting marks inside around a dark UV center, all invisible to us humans but clearly visible to bees, and all this gets nicely visible here, also in simulated bee vision.

I have written about this Gazania previously HERE
