Today about some Lichen (most likely Xanthoria parietina and Physcia adscendens grown into each other), that I found growing on a broken branch. Shots in UV were done using my CERCO 94mm quartz/fluorite lens, the UV Baader-U and bee vision XB4 filter as well as a modified Xenon flash was used as light source.

Quite interesting, how Lichen reflects UV light in these differently colored sub-UV bands I have written earlier about. Nice to know a target for UV photography when flowers will be gone soon...
HERE it is in UV induced visible photography.
Stay tuned, more will follow on that fascinating subject...
