Publisher using my multispectral works in a third edition Psychology Book

Today about a forthcoming 2027 third edition book "Interactive Psychology  - People in Perspective" by James J. Gross (Stanford University), Bridgette Martin Hard (Duke University), Annie Stanfield Ditta (University of California, Riverside), Toni Schmader (University of British Columbia) and Adam K. Anderson (Cornell University) will again be using some of my multispectral photographic works to illustrate different visions.  

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.

This Gazania's outer petals strongly reflect UV around 365nm, whereas the inner petal parts are quite darker, hence forming UV nectar guides for UV seeing insects. There are also some highly UV reflecting marks inside around a dark UV center, all invisible to us humans, but clearly visible to bees and butterflies, and all this gets nicely visible here, also in simulated bee and butterfly vision.

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

My work for France TV "C'est Toujours Pas Sorcier : Les superpouvoirs des abeilles" II

France TV will  - again -  be using my multispectral works in their programme  "C'est Toujours Pas Sorcier : Les superpouvoirs des abeilles".

Those multispectral images of mine where shot in my studio and outside with my "work horse" UV-Nikkor f4.5/105mm quartz fluorite lens using the Baader UV/IR Cut filter and my proprietary XBV filters for simulated bee vision. Light source in studio used was a Xenon flash modified for high UV output and sunlight outside.

All these flowers have very specific UV patterns; the outer part of their petals are UV reflective around 360nm, but their inner parts show a UV-dark area which gets nicely visible. And I assume the TV viewers will be surprised to see all that...

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

Museo de Ciencias Universidad de Navarra Spain exhibit "Colour: An Explosion of Science" showing my works

Today about some of my works being used with my permission by the Museo de Ciencias Universidad de Navarra, Spain soon visible in their forthcoming exhibition "Colour: An Explosion of Science" October 8, 2026 until February 7, 2027.

https://museodeciencias.unav.edu/exposiciones/color-una-explosion-de-ciencia 

Their idea was to show especially children how the flowers have developed a strategy invisible to us how to efficiently interact with bees and butterflies using reflected ultraviolet (UV) light.

They chose to use my images of attractive flowers, like Rudbeckia, Zinnia and Gazania, which were shot by me in visible light, in reflected ultraviolet light and using my special filters to simulate bee and butterfly vision.

All those flowers have outer petals which strongly reflect UV around 365nm, whereas its center parts are quite darker, reflecting around 365nm, hence forming invisible to us humans UV nectar guides for UV seeing insects. This is all invisible to us humans, but clearly visible to bees and butterflies, and all this will be nicely visible to the visitors at the Museo de Ciencias Universidad de Navarra.

Black-eyed Susan - Rudbeckia hirta in 3D reflected ultraviolet photography and simulated bee and butterfly vision XX

Today more shots of that beautiful flower, originating from the USA Prairie, here today again that commercially sold hybrid of a Black-eyed Susan - Rudbeckia hirta (possibly R. hirta x R. fulgida) in 3D STEREO (crosseye) in reflected ultraviolet photography using different filters aside from the Baader-U filter, but different ones today for simulated bee and butterfly vision but also part of my XBV filter set. All shots were done at f8-f11 on my balcony. Lens was a UV transmitting 35mm wide angle lens with an older Zeiss Jena Macro beamsplitter. Light source was direct sunlight.

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 in 3D STEREO.

I have previously written about that flower HERE

Partial Eclipse 2026 recorded in Germany in reflected ultraviolet light

A partial eclipse has happened August 12, 2026 visible in Germany - and on my new location in south-west Germany with around 86% visibilty I had decided last minute to try and record that. So I prepared a setup consisting of my modified Lumix GH4 plus a lens I found a while ago which surprisingly does transmit UV light: a f4/250mm catadioptric lens. A bit tricky is using a suitable UV transmitting filter with that lens, as it has to be mounted into the rear lens mount, which worked using a 25mm diameter UV filter stack (centered at 370nm) I found at a US seller years ago with rather good VIS/IR suppression.

Surroundings in reflected UV (370nm):

Trying to white balance this last image lead to some interesting, bit eery effect:  

So this went rather well, even a sunspot got visible (click on the first image to see a larger one), so I was rather happy to have captured such a rare event, the last one visible here in Germany was 1999.

Common Sunflower - Helianthus annuus in reflected ultraviolet photography and simulated bee vision III

Today in my new location after the move more shots of a flower everybody has already seen, a common Sunflower - Helianthus annuus in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was daylight through the windows plus some supporting 365nm UV LED light. All shots were done at f8.

This flower has a specific and unique UV pattern, its petal tops are brightly UV reflective around 365nm and the rest and its center is UV dark forming an UV bullseye pattern, and all this gets nicely visible here.

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

Today more shots of that beautiful flower, originating from the USA Prairie, here today again that commercially sold hybrid of a Black-eyed Susan - Rudbeckia hirta (possibly R. hirta x R. fulgida) in reflected ultraviolet photography using different filters aside from the Baader-U filter, but different ones today for simulated bee and butterfly vision but also part of my XBV filter set. All shots were done at f8-f11 on my balcony. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was direct sunlight. 

PS: These other filters (filter stacks actually) I used have partially corroded over time, so I had to polish them using finest Cerium-Oxide powder. I made some slurry with that using filtered water, then polished the filter glasses with that using a very soft cloth and small circular movements, then rinsed them clean and dried them. So these images hopefully prove that this was successfully done....I think so.
