Lichen: human vision vs simulated bee vison; reflected UV ultraviolet photography II

Today again about that same 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 an older approx 85mm quartz/fluorite lens, the UV Baader-U and XNUV filter, the bee vision simulating XB2 and XB4 filter as well as a UG11 + S8612 (cladded, 2mm) filter stack. My modified Xenon flash was used as a light source.

Quite interesting to note that also this old quartz / fluorite lens nicely reproduces, how Lichen reflects UV light in these differently colored sub-UV bands I have written earlier about. Really nice to have that target for UV photography when flowers will be gone...

HERE it is shot using my CERCO 94mm quartz/fluorite lens and HERE in UV induced visible fluorescence..

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