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

Today the same shots - but developed from RAW files using Capture One PRO - 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 a Xenon flash. All shots were done at about f5.6.

Bidens has a strong visible UV pattern, its petal tips are UV bright around 365nm, its center is quite UV dark, so this gets even nicer visible developed from RAW files.


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