Today again about that same Lichen I have reported about (most likely Xanthoria parietina and Physcia adscendens grown into each other), that I found growing on a broken branch. Shots now were done in UV induced visible fluorescence (UVIVF) using my CERCO 94mm quartz/fluorite lens, the Baader UV/IR Cut filter as well as my Nichia high power UV LED system that was used as a light source.

Quite interesting colors get visible. So also that is nice to know as a target for UV photography when all flowers will be gone soon...
Stay tuned, more will follow on that fascinating subject...
