The expression „new wine“ is ambiguous in the German language. On the one hand, this refers to grape juice that has not yet begun to ferment. On the other hand, this means the freshly harvested grapes.
By chance we were given a delivery of fresh harvested grapes of the Pinot Noir variety, which we immediately subjected to an X-ray examination. An additional photograph of the composition from below the exit point of the X-rays was taken quickly with a Leica Q.
The result of this image fusion is shown here:
Grapes as an object of X-raying have been inspiring me for a long time. Their structure remind the doctor of the azini of a gland or lung. The phycisist likes very much the partial and complete overlays alternating with free positions. As an artist I get an unbelievable freedom of image design.
My first X-ray imaging attempts with grapes were carried aout in October 2017. I’d forgotten !
Can something succesful be repeated ? Can it be deepened ? What is the power of the composition ?
Two days ago I tried toput my creativity into the composition. Two pictures were taken from grapes which differ only slightly. Their X-ray view on our monitor had a clearly different effect.
My colleague by chance showed up with a bouquet of small sunflowers with long stalks. Amazing opportunity !
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.
Here is a comparison of X-ray on the left side versus Mammography on the right side. A Belgian endive and a lettuce show much more contrast and fine structure in a mammography whereas X-ray gives more the impression of softness. Which goes well for a salad.
Onions have a lot of liquid and are therefore radiopaque. I was curious to see which method would make it better to reveal the layerstructure of the onions. To my surprise mammography did a pretty good job.
Conventional X-ray offers more mystery, especially when you stack onions.
Some kind of layered structure also has fennel. I got two specimen that looked like mittens.
This year we had so many apples in our garden. They are red and look juicy. I had the chance to take two of them to my X-ray machine. With the help of two different orientations an interesting picture succeeds, because on of the apples still has a small branch.
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.
A friend gave me a shell of a spider conch to make more fusion images. The scientific name of the spider conch is lambis lambis and it is a sea snail. There is a nice Wikipedia article on it.
The hard shell with a lot of radiopaque lime made me doubt the success of my X-rays. On top, my first attempt at a HighKey image wasn’t really convincing. Only the combination of a normal photography for the color, a HighKey image for a transparency effect together with the X-ray image resulted in nice image.
The X-ray image appear less lively, but full of formal power. The orientation of the animal is conveyed by the photographically reproduced color. There are only minimal hints wich orientation the X-ray has.
These are the corresponding X-ray images:
It feels like very long ago. Harold and I were taking the shots and X-rays of new compositions last week of April this year. Our first try was an orchid with two stems. The transparency effect is very much augmented using an X-ray. A stem behind petals doesn’t show easily in HDR light box photography.
With a Phase One camera at my disposal a strong crop of the composition shows the tenderness of our orchid much better. With a resolution still sufficient.
Since 1905 there is an X-ray meeting in Germany. It was the 100th time this year. Nowadays the convention takes place every year.
Besides the scientific news the convention offers the opportunity of caring for personal contacts. It is part of the beautiful things of the convention to meet old acquaintances and to exchange with them.
Leipzig fair is a great environment for this event. An agreeable tiredness affects me at the end of the day after many positive conversations. I left the celebration with relief.
Clematis is a reliably blossoming flower in our garden. Every year we look forward to her blooms for many weeks. Photographing flowers means sacrificing beautiful little things. It took me some time to go there.
With growing experience I feel less pain to sacrifice a bloom for artistic purposes. It relieves me a little, that I have the blooms swum after my photo and X-ray sessions in a soup-plate filled with water which is in the kitchen. Many people like the floating blooms in a soup-plate, if they are in a break.
The HDR series of my composition with three clematis gave me a hard time. Although a tripod is indispensable and always used, a small pixel shift between exposures was perceivable. After fixing this, light, color and structure was processed for an HDR image.
The X-ray of the three clematis was performed as mammography due to the size of my composition. The fusion image can be understood as a texturized HDR by means of a radiograph. But there is no unique solution to all compositions. The best solution has to be found out individually.
After all, the clematis look as light as a feather in this image. It was worth it.
First flowers in spring show up. With much support from my colleagues I’m able to do some fusion images. We all would like to have another calendar.
Preparing the lightbox, the X-ray machines, my camera and picking out the data is a bunch of hassle.
My personal favorite is the blue cornflower. It looks like a print of an old botanic book:
The next day I turned my attention to our white and blue Aquilegias. No chance to process the raw data yesterday. Eventually, there was a chance today, after quite a bit of tedious work at my desk:
Fusion imaging is a method full of surprise. My red calla lilies revealed an effect I had forgotten completely. There must be a gradient in every X-ray exposure.
Preparing a fusion image composition with my 6 red calla lilies I found a troublesome gradient in the X-ray.
The cause for the gradient is a weakening of X-ray radiation at its origin in the X-ray tube. A closer look at the phenomenon can be found in my FAQ. This effect of variable recording of photons phycisists call „anode heel effect“.
As part of my creative process I rotated the composition shown above by 180 degrees and exposed it a second time with the same parameters. Note that post-production as well was done equally for both X-ray exposures !
Sometimes reality falls behind our expectations. With 6 red calla lilies I felt well prepared to do some new X-rays and HDR images for image fusion. But my X-ray system surprisingly raised a barrier. The main computer stopped doing his job.
Many thoughts ran through my brain. Will we be able to examine patients the next day ? How fast the supplier will be able to react ? Will the company find a cause of this disturbance ? How many days will my calla lilies be alive ?
I found a work-around by thinking over the interacting hardware. Doing some steps and with a newly restarted system I was able to create 7 different compositions without further disruption of which I show here No. 4.
With X-rays emerges a more impressive illusion of transparency than a plain HDR would have been able to produce. Even when using a lightbox.
Similar to a lightbox it produces better results when laying a petal or a complete blossom over the top of the stalk of another one.
On top of the longest stalk is a twin blossom !
You never know if the inversion in Lab colors leads to an attractive result. It’s always worth looking at Lab color transformations. In this case the black background yields vivid colors.
