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...

Lichen: UV induced visible fluorescence and reflected UV; ultraviolet photography

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 that I have shown in reflected UV and UV induced visible fluorescence. So here a quadriptych of VIS-FL-UV images, just for viewing pleasure and of course also for comparison.

Quadriptych VIS-FL-UV:

Well, it seems that a little broken branch laying in the mud, can have quite some hidden and invisible beauty, that was just waiting to be revealed...

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

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...

Negative Space used by Eschscholzia californica (California Poppy): UV ultraviolet photography

Today about Eschscholzia californica (California Poppy), which makes use of a very interesting concept: Negative Space. I made those shots at Herrmashof Park, Weinheim, Germany using a custom made up UV lens from a simple quartz singlet that I used before, stopped down mildly to various degrees to control a wanted soft focus effect. Shots in UV were done using the Baader-U filter and sunlight was used as light source.

The most interesting part, aside that soft focus effect was for me, how this California Poppy uses its pitch black petals (in UV) to make its anthers stand out brightly against that dark background by massively increasing contrast. To help attract pollinators? I would guess so...


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

Gazania rigens: Quartz Singlet Lens for Soft Focus Reflected UV Ultraviolet Photography III

Today a set of shots with a Gazania rigens flower that I have shot previously with a quartz-fluorite lens now using a custom made up UV lens from a simple quartz singlet that I used before, stopped down mildly to various degrees, so as to control a wanted soft focus effect. Shots were done using the Baader-U filter and sunlight as light source and "contra lucem".

So, I'm sure this is not to everyones taste, but on my way to explore other possibilities then just "scientific" shots, it is a welcome new style.

Part II is HERE

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

Gazania: Quartz Singlet Lens for Soft Focus Reflected UV Ultraviolet Photography II

Today a set of shots with a different Gazania rigens flower that I have shot previously with a quartz-fluorite lens now using a custom made up UV lens from a simple quartz singlet that I used before, stopped down mildly to various degrees, so as to control a wanted soft focus effect. Shots were done using the Baader-U filter and sunlight as light source on my balcony with some glass mirror effect.
