Apache beggarticks - Bidens ferulifolia in reflected ultraviolet photography, simulated bee and butterfly vision II

Today shots of a spring flower I have written about before, Apache beggarticks - Bidens ferulifolia 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 CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
 

Simulated butterfly vision (UV - VIS) using XBV3 filter:
 

Simulated bee vision (UV - VIS) using XBV6 filter:
 

Quadtriptych of some of the above:
 


Bidens has a strong visible UV pattern, its petal tips are UV bright around 365nm, its center is quite UV dark, so this gets quite nicely visible.


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

Apache beggarticks - Bidens ferulifolia in reflected UV ultraviolet photography

Today about a quite well known spring flower, Bidens ferulifolia or commenly named Apache beggarticks in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter. Lens was a CERCO 94mm quartz fluorite lens. Light source was Xenon light. All shots were done at about f5.6. I have written about that flower last year and also measured its special UV reflection using my spectrophotometer as well as I have shown it in various spectral bands and simulated butterfly and bee vision.
