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...
