Dwarf Tulip - Tulipa pulchella violacea in reflected ultraviolet photography, simulated bee and butterfly vision II

Today also about an early spring flower, I have written about before HERE, a Dwarf Tulip (Tulipa pulchella violacea) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at f8.

Quadriptych human vision, UV, sim. butterfly vision, sim. bee vision (left to right, top to bottom):

 

This dwarf tulip has a quite visible UV pattern, its center is UV bright, surrounded by long ware UV reflecting tips and this gets quite nicely visible.

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

Rock tulip - Tulipa saxatilis in reflected ultraviolet photography, simulated bee and butterfly vision III

Today some shots of an early spring flower I have written about before, a Rock tulip - (Tulipa saxatilis "Lilac Wonder") (often wrongly labeled T. bakeri) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at about f8.

This rock tulip has a not so strongly visible UV pattern, its petals are UV bright, and this gets quite nicely visible in these close-ups.

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

Marsh marigold - Caltha palustris flower in reflected UV ultraviolet photography and simulated bee and butterfly vision IV

Today shots of a spring flower I have written about before, Marsh marigold (Caltha palustris) in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at f8.

This Caltha flower has quite a prominent UV pattern, its center is UV dark, as well as some UV dark veins on its petals. The bee vision image additionally reveals some lit up anthers and all this gets quite nicely visible.


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

Science Center Singapore 2016 exhibit about butterfly vision II

The Science Center Singapore  will open an exhibit in 2016 which will include a showcase about butterfly vision. Some of my Treasury flower - Gazania rigens images will be used for this purpose, as these clearly demonstrate the difference between human and insect vision.

They have chosen my work, as it "shows a great and interesting contrast between how we usually see this flower, and how the same flower might be perceived by a butterfly, particularly the colours and directional markers"

I have written about this flower and how this was photographed HERE
 
Stay tuned, more will follow on that fascinating subject...
