Reflected UV shot using Baader-U filter, simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Alright, green petals and cyan leaves, what colour the sky and Sun. The buzz is, they use it for navigation?

high resolution close up shots....

Visible light image:



UV image using Baader-U filter (UV):


Simulated bee vision image using experimental XBV filter (UV, blue, green):


Triptych of the above images:



This attractive flower in macro close up even more so shows its very specific UV pattern,
its petals have a UV dark pattern, invisible to us humans. It also shows the conical cell
structures that enable insects to have a better grip on the surface when landed..
