Cloisonné ceramics in reflected ultraviolet and simulated bee vision photography

Today about ceramics, Cloisonné especially and reflected UV photography. I have three different objects here as targets, from Thailand and India. For that test I'm using my the UV-Nikkor 105mm, as well as my "work horse" UV filter, the Baader-U filter and my bee vision simulating XBV6 filter. Light source was a modified Xenon flash. All shots were done at f11.

Interesting to see how in reflected UV light and especially in simulated bee vision imaging, the center piece shows otherwise invisible patterns.


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

Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography and simulated butterfly and bee vision XXVI

Today first shots of a very decorative summer flower in 2016, Mexican Zinnia - Zinnia haagenea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated butterfly and bee vision using my proprietary XBV filters. Lens was my UV-Nikkor 105mm quartz flourite lens. Light source was sunlight. All shots were done at f8.

Mexican Zinnia flowers have a very specific UV pattern. Their petals are very UV dark in the middle and bottom, their petal tips, however, are very UV bright (around 365nm outer tip), and all this gets nicely visible, also in simulated bee and butterfly vision.

I have previously written about those Zinnias HERE

Bermuda Buttercup - Oxalis pes-caprae in reflected ultraviolet (UV) and photography and simulated bee vision

Today about a very common weed flower Bermuda Buttercup - Oxalis pes-caprae I shot shot at Mountain Vew, CA in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz fluorite lens. Light source was sun. All shots were done at f8.

Bermuda Buttercup - Oxalis pes-caprae in Human vision, reflected UV, simulated bee vision (left to right):


This attractive yellow weed flower shows quite a tricky UV pattern, as shown in the following enhanced reflected UV image, a UV bright ring set on a negative space around the dark in UV petals, hence massively increasing contrast. Plus you also see the pyramidal cells in this enhanced resolution image (UV gives approx. 1.6x higher resolution) , which allows pollinators a much better grip while being at the flower.
 

All this invisible to us humans, but visible to bees and butterflies, and all this gets nicely visible here.
