Bidens ferulifolia: Colorful reflected UV ultraviolet photography III

Today, as has been previously shown,  some more recent results with a bit more colorful images using various UV lights and filtering, when shooting in reflected UV light. I was using my "work horse" UV filter, the Baader-U filter and my CERCO quartz fluorite lens. Light source was an UV enhanced Xenon flash, except otherwise mentioned. Target was one of my last Bidens ferulifolia flowers, as the first snow has already been here...

Now this is "artsy" playing with light, but it still documents very well the prominent UV pattern this flower has. HERE is the same flower in 3D Stereo representation.


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

Carl Zeiss Jena Lamegon 38mm: UV ultraviolet photography II

Well, I dug out this lens last weekend and took a few shots with it again, when I remembered that it can also be used for UV (and IR) despite its complex 8e/4g lens design incorporating lots of glass elements and a few cemented ones, based on the famous Biogon design of Dr Bertele. In my first Blog entry about this lens about a year ago I was referring to my friends site about such special and rare lenses HERE and there are also some UV and IR shots.

So today about UV photography using this lens, executed using one of my last Rudbeckia fulgida flowers. Shots were done using the UV Baader-U and XNUV filter as well as the bee vision simulating XB4 filter. My modified Xenon flash was used as a light source. Oh, and no focus correction was done!

Well, the UV transmission is not that great, as may be seen from the colors of the second to last image, but still quite useful and especially sharp. So, maybe you you understand why I was so surprised again about the performance of that lens - no wonder its larger brothers (8/110mm and 5.6/55mm) were used in cold war as a aerial imaging lenses. And btw. if you like to see how amazingly this lens performs in the visual, have a look HERE from 2011 and HERE from this year.

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...

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.

Unfortunately these bread Zinnias don't show that prominent deep UV patterns as the mexican Zinnia haagena do ... oh well, not all what artificial breedings does leads to pleasant results.
