Spring Flowers 2014: Tussilago farfara - Coltsfoot - 80mm Quartz Fluorite lens for reflected ultraviolet photography II

Here now more studio shots of that well known Tussilago farfara - Coltsfoot early spring flower. Shots were done aside from visible photography in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens used was my X80QF f3.2 / 80mm Quartz Fluorite lens. Light source was a modified Xenon flash. All shots were done at approx. f8.

Triptych of the above images:  

This Coltsfoot flower has a well known bulls-eye UV pattern, its center is UV dark, whereas its petals strongly reflect around 365nm. This older quartz fluorite lens is reproducing this quite well also in the studio and all that gets nicely visible.

There are "in situ" shots of that flower HERE.

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