Lichen: human vision vs UV induced visible fluorescence vison and reflected UV ultraviolet photography II

Today more about that piece of bark with Lichen growing on it (most likely Xanthoria parietina and Physcia adscendens grown into each other), that I found blown over onto my balcony. Closeup shots in reflected UV, visible light and simulated insect vision were done using my UV-Nikkor 105mm quartz/fluorite lens as well as another quartz-fluorite lens reversed as a multispectral diopter. Filters used were the UV Baader-U filter and my usual XBV filters. My modified Xenon flash was used as a light source.

So this Lichen bark in closeup was a quick experiment, quite some room for improvement of course, possibly using stacking in future for more DOF.

I have written more about that HERE.

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