New X-ray fusion photo compositions
New year, new ideas. A superbe bowl of fruits inspired me to do more X-ray fusion photography today. I got a bundle of bananas, lots of lychees, two pears, figs, an apple and a pomegranate.
I changed my technique a bit. There is no chance to get a transparent banana image using a photo. But mixing the colors of the photo with the X-ray is also a fusion image. To my opinion, the bananas came out lovely, especially the color of the trunk.

The following fusion image is resulting:

Vegetables X-ray photography
Harold implanted the idea of X-rays with onions in me. Although more than covered with professional requirements, I tried my hand at vegetable x-ray photography.
I can say it’s fun. Although a defective screen had to be replaced at the beginning. And you need some patience. Not every shot shows its beauty from the beginning. Some have to be developed first.
Let’s start with a corncob. It has many outer leaf layers, which lie close to it. X-rays look through and show the layers at the edge of the bulb as fine lines.

May be there is some truth in the saying: an apple a day keeps the doctor away. But as the dentist would say: no teeth, no apple.

Karl Blossfeldt was a German photographer who lived from 1865 to 1932. He didn’t think himself a photographer. With his studies of plant forms he made an enormous contribution to plant photography. Here is a nice wikipedia article about him.
He started to do photograms. Plants or parts of plants were placed directly on film or paper suitable for exposure. Exposure then takes place without any optics. Later he built himself a wooden camera, which reminds me of Andreas Feininger.
Black and white backlit macro images with a background can be similar to Blossfeldt’s images.

Imagine a Nautilus shell tilted to the surface of the X-ray sensor. The parts close to the sensor are sharp, the distant parts unsharp. Because the X-ray beam creates a central projection. The focal plane is the plane of the sensor, in focus are those parts close to the sensor.
The shell looks like entering the image or leaving it.

How to show the sun in the middle of a sunflower ? For astronomers it is quite common to look at the sun in hydrogen alpha light, which is a pure red at 635nm. With artistic eyes, a red center might be overdone.
So I tried two different representations, one in BW that is close to the natural look and feel of a sunflower and one with a light blue in the center as complementary color to the yellow petals.

There is no photo of the next digital X-ray image of a sunflower with its stalk and a leaf:

Our weather is more and more weird. Today was the second day with a warm sun and a blue sky. Nights are getting pretty cold, days up to 25 degrees Celsius.
Cleaning up our garden led us to some old physalis which were a little more than a skeleton. In autumn these fruits look like lanterns, now they resemble an X-ray.
I did this shot on a lightbox using manual HDR technique.In Lab color mode I obtained this image with a pur black background.
It’s an exoskeleton for the fruit inside which remains that way without bruises.

How to communicate an erratic process in terms of an image ? The Iliadic greek were pirates of the Mediterranean with fast vessels, invading mainland from the seas, enslaving people, robbing stocks and much more.
The writing down of the Ilias was between 678 and 662 B.C., a time of Assyrian dominance and cultural superiority.
With three different Nautilus shells I bought last September on Crete I did this composition on my big X-ray sensor with 35cm x 43 cm and 170µm per pixel resolution. Two energy levels were necessary to get a high resolution image of the core of the Nautilus shells.
Odyssey © Julian Köpke To overcome the look-and-feel of a medical X-ray it is a logical idea to invert the light. Black becomes white and vice versa. White means shining through of X-rays, black means opacity. It’s like a dream !

How to prepare a X-ray session ? What flowers suit to a Nautilus shell ? Where does color come in ?
I went to my gorgeous florist to have a look what offer she can make during wintertime. My phantasy were spinning around something ethereal or unrealistic. I bought some flowers with respect to their shape.
The Anthuria caught my eye immediately. The Tulip was still closed and got more and more yellow within hours.
All these compositions shown here were made with dual energy X-ray. The lowest energy of the tube is 40kV, which yields with 4 mAs a quite good insight of flowers. For the center of the Nautilus shell, 70kV and 2.5 mAs is more appropriate.
My first composition was a Nautilus taking off a bouquet of flowers. This reminded me of Renaissance engravings full of symbols. I do not feel depressed. The representation as a X-ray positive jsut shows the bouquet.

The positive representation always needs some extra editing. By just inverting the Blacks and the Whites the Nautilus would be too dark. Our reception cannot be just inverted and feels alright.

It took me some time to mask out the flaws of an original X-ray to get a true black background. Masking can be done iteratively and easily combined with Photoshop. („That’s what Photoshop is made for !“).
Some colorizing was done to overcome missing photographic shots. There was simply no time in my X-ray unit to do both at a time.

The Nautilus shell serves as Argo, the legendary fast ship, with its crew, called Argonauts. The colored version is more convenient for our eyes. As before the X-ray positive looks more ethereal.

Is there poetry in a landscape ? Does an image give the impression of poetry ? These questions came up when looking down from the Zugspitze at the Alpine folding.
It was a cold day with with warm rays from the sun. No winds, except at the border to Austria. We were lucky to spend a few hours up there at about 2960m.
This folding was soft and wild at the same time. Is it a solidified sea ? A petrified curtain ? Only the light creates the feelings.
