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.

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...

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.

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. To attract pollinators? I would guess so...

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.

Zinnia: UV Induced Visible Fluorescence - ultraviolet photography III

So, last few of those Zinnia examples that I have shown before indicating what could be done with Nichia based NC4U133 (365nm) / NC4U134 (385nm) systems and my High Power UV LED Radiation System with easily exchangeable radiation heads for nominal wavelength of 365nm, 385nm, 395nm, 400nm and 405nm using the most modern 40W UV LEDs or the simple and now quite common 365nm Nichia flashlights which use the single dice NCSU033A and NCSU033B chips.

I hope these shots also serve as example what could be done with those UV flashlights, but of course those are useful for many different applications such as stimulating visible fluorescence, reflected UV photography, forensic, dermatological and dental examinations and photographic recording, curing of UV glue / bonding, as well as leakage detection etc.

Nichia 365nm flashlight: Beam Homogenizer for reflected UV photography and UV induced visible fluorescence

Today, after having previously shown the Nichia based NC4U133 (365nm) / NC4U134 (385nm) systems and my newest High Power UV LED Radiation System with easily exchangeable radiation heads for nominal wavelength of 365nm, 385nm, 395nm, 400nm and 405nm using the most modern 40W UV LEDs, I present something much easier: a simple beam homogenizing solution for the meanwhile quite commom 365nm Nichia flashlights which use the single dice NCSU033A and NCSU033B chips.

After a long search I finally located a specifically designed beam homogenizing solution that sufficiently transmits UV and allows to generate a quite even radiation field, which is beneficial to have, especially for photography which usually requires even illumination of the target.

I have also tested it working with the newer 4 dice Nichia NC4U133 (365nm) and NC4U134 (385nm) chips, but those are not used for portable flashlights yet as far as I know.

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

Bought a few Zinnias today from my friend Christian Mayer, a very creative florist here in Weinheim, Germany. I'll show this bouquet of various Zinnias in multispectral representation. These shots were taken using inside using my Xenon high power flower flash in normal human vision VIS, in UV using the Baader-U and Jupiter-U filter, as well as in simulated bee vision using my XBV2, XBV3, XBV4 and XBV6 filters respectively as well as the new XNUV filter.
