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...
