Hortensia - Hydrangea in reflected ultraviolet photography, simulated bee vision

Today shots of an well known flower, a Hortensia - Hydrangea in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

This Hortensia flower has a not a very specific UV pattern, its petal rims are lit up in UV, its center is a bit darker and this gets nicely visible.


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