Here now UV-VIS differentials on the right side.

This lens is so sharp, already fully open, so stopping down is only needed to control the DOF (depth of field).


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

[VIS, UV] Late Summer's "Grand Finale" - Zeiss UV-Planar 60mm

Today summer came back and flashed his intensive golden rays over our wonderful Hermanshof Park here in Weinheim, so I grabbed my system and took a few shots. Without more ado, have a look in VIS and UV...

[the yellow flower is Helianthus tuberosus and the violet flower is an Aster type]

[UV, VIS] Spring Daffodils meet ZEISS UV-Sonnar 105mm

Today some experiments using a ZEISS UV-Sonnar 105mm, Hasselblad 501 C/M body and Phase One digiback. Target were some spring daffodils which had just started to flower.

So here side-a-side the VIS and UV shot:


[that "black" background cardboard I was using was not black in UV]

Not much to see in UV except the lit tips on the petals and the structure on that petal surface which gets visible.


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

[UV] Lilly "retro style" using UV-Sonnar 105mm and Polaroid film

Today a leap back in time. Let's dig out the old photo gear and see what could be done with that. Let's go retro!!

So I grabbed my Hasselblad 500C/M, my UV-Sonnar 4.3/105mm, that special Schott UG11 UV transmission filter that came with that rare lens, a Polaroid back and some Polaroid 100 bw film (good till 1987, just "a little" outdated I have to admit). Exposure was ISO80, 1/125, f8 using a 400Ws Xenon flash.

Considering the effort and hit rate, I know now how spoiled I am shooting digital!! Same done digital here.

Carl Zeiss Jena 60mm UV-Objektiv and Rudbeckia

So today I dug out my old Carl Zeiss Jena f4 60mm UV-Objektiv (a simple triplet actually, made of UV transmitting glass) mounted it with a suitable helicoid to an Olympus E-510 DSLR, and repeated the reflected UV and fluorescence shots as yesterday.

As light source a 365nm UV LED was used here and no other modifications were done. Here the UV shot using the Baader 2" U-filter (320-390nm), just color balanced to taste, no other modifications done. Interesting to note that since this lens is a simple, yet sharp triplet design, quite some massive focus difference between visible focus and UV shows, nearly 50mm in this case (closer for UV). [actually also the reason why the UV image is somewhat larger]




The second shot I used the same UV LED, but the filter used was the Baader UV/IR Cut filter, to suppress UV and to allow for fluorescence.



Oh, and if someone wondered how that flower looks like in normal white light, there you go...



Did you notice these aphids wondering around...? It seems to grin right into the lens on that last shot!

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