Lichen: UV induced visible fluorescence; UV ultraviolet photography

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...

More info on this very interesting field may be found on my site
