Winter Jasmine - Jasminum nudiflorum in reflected ultraviolet photography and simulated bee vision III

Today even more shots of a decorative winter flower Winter Jasmine - Jasminum nudiflorum in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens used was an older fast cine lens lens. Light source was Xenon flash. All shots were done at f8. This time the UV image was individually whitebalanced.

Triptych of the above images:  

This attractive winter flower shows its very specific UV pattern. Its center is UV dark, but its petals are strong UV reflective around 365nm, ie. UV bright, both invisible to us humans. Also this older cine lens is reproducing this quite well and all that gets nicely visible, here now matched to the CERCO quartz fluorite lens results.

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