Sunflowers are a common UV test subject. On their own, they are photogenic enough for any kind of spectral treatment.

Panasonic GH-2, W-Nikkor 3.5 cm f/3.5 lens, Baader U2" (venus) filter.

Two tall Joshua Trees loom large in the US desert.

Nikon D40X, Fisheye-nikkor 7.5 mm f/5.6, Baader U2" (Venus) filter. This version is cropped to cut off the black corners due to the fisheye's image projection being too large for the DX format.

This was one of my first successful digital UV photos and was printed double-page spread in a magazine article some years ago.

A very keen observer might recognise the partly submerged stone as the same featured in post #39. Lake levels were higher for the present shot though.

From the series I shot on assignment for Jenoptik, maker of the famous Coastal 60 APO, to be used for their booth at PhotoKina. The point to make was of course the superior lens quality over a very wide spectral range essentially without any focus shift, thus making alignment of partial images a breeze.

Nikon D200, Coastal Optics 60 mm f/4 APO lens, multispectral filters UV-Vis-IR

Thanks Bjørn. Extremely interesting, inspirational and mind-blowing.

Thanks, Paco.

Not nearly done, however.

French Nymphaeas with a single flower and plenty of lily pads.

Nikon D40X, Voigtländer 180 mm f/4, long exposure thus a little blurring of some of the pads.

Børge, what happens if we pull the plunge and don't produce as master Bjørn does?
A huge possibility  ::)

Comparing your work to Bjørn's is never a good idea, especially in the UV realm  :o

When you get frustrated working with UV you can always just hang your camera out the window of a moving car and hope a rock smashes through your lens

A good rule is never try to bite over more than you can chew. Applies to UV as well.

Thanks go to Jan Anne for being the ever patient model while I experimented to see if I could get enough UV through my 14-24 Nikkor.

One of my earliest digital UV image.  The camera was D2H, and the lens was Seires E 35/2.5 I think.  Perhaps I hadn't yet acquired the BG 40 filter when I shot it.  The only filter I put in front of the lens was Kenko/Hoya U-360.  There should be massive IR contamination, but the bull's eye patterns of the "free" dandelions are evident.  ;)

Earlier digital UV had a lot of out-of-passband contamination. Thus it is well-nigh hopeless to make these files appear like what we can acquire today.

For pictorial UV, little or no harm is done anyway, as there are no rules set in stone at play here. For more exacting comparative studies on say UV signatures and patterns, one need much better control of what spectral regions are recorded by the camera.
