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:

X-ray Xmas floral arrangement
Today was a day of dense work and many technical problems. The day before I had made some flower arrangements for Christmas from my preferred flower dealer. A technician took me some X-rays so I could study the exposure values when my wirk was finished.
The following two I liked most.

X-ray fusion photo of a sphere of snail shells
This X-ray fusion image is untrue. No time during working hours to take the photograph. So I made a photo this morning at home. There are so many snail shells glued on the sphere that it is basically not noticeable if the rotation does not match exactly.
Here is my result:

X-ray photos of grapes and sunflowers
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.

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.

Purple Clematis
Long lasting blossoms, turning up every year: my purple clematis in our garden.
It was my third X-ray session with flowers this week. Third fusion imaging attempt. After blue cornflower and blue aquilegia now a purple clematis. Big data on my hard disk.
Today we did it with mammography at 30 kV and 50 mAs. Lower noise ! Here is the positive representation of a single clematis:
Clematis X-ray photo © Julian Köpke I processed the lightbox HighKey series with a mask. There was a shift of 2 or 3 pixels from the lightest to the darker images. So I processed everything a second time to compensate for the shift. The HDR image shows a cut stalk. Photoshop is made for this.
Purple Clematis © Julian Köpke The stalk can be lengthened like in the preceding X-ray. The fusion image shows hidden leaves, the core of the blossom and stalks much better:

Spring and X-ray fusion photos
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:

Red calla lilies
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 !

Red calla lilies
With my new glasses in my pocket I gazed the nearby market place on Saturday. I was captivated by six red callas whose price I could knock down to 10€ for all of them.
With my Zeiss 50mm Macro lens and no tripod I was trying to get nice shapes late in the evening. The following images have been processed using Lab color to enhance contrast and colors.
