Arie's x-ray images are not composed of different layers. "It is not a composition of different x-rays. No stacked images. Not assembled. The complete setup of the natural scene (biorama) with animals and flowers is built and x-rayed in one session as a whole. I apply an analog technique and use Silvergelatine x-ray negatives. Kodak X-Omat V 33cm x 41cm."

Arie's idea to x-ray flowers and animals was born in the hospital. "I was involved in the teaching program on radiation physics and radiation safety for radiographers and physicians. I think in 2000 I started to challenge the students to x-ray flowers. It was a nice exercise demonstrating that even very thin objects can be imaged by x-rays. For this application, very low-energy x-rays were required. So it was for educational reasons that I started to x-ray flowers.

In 2007 I got my own studio with x-ray equipment. From that moment on I started to build complete nature scenes (bioramas) with plants, flowers and (dead) animals. I x-rayed the bioramas, digitized the greyscale x-ray negatives and partly colored them with Photoshop. So, I think 2007 is the starting point of my artistic x-rays."

If you wonder how these images are made exactly, Arie has an elaborate explanation for you!

Firstly, the artist samples plants, flowers, dead animals, etc. All the collected objects are then arranged upon an x-ray negative (33cmx41cm), packed in a light, tight envelope. This staged natural scene (biorama) is placed on the floor, the x-ray tube is positioned at a distance of about 1m above it. Beam on and an x-ray is made.

Afterward, in a dark room, the x-ray negative is taken out of the envelope and is put into the processing machine, resulting in a black and white x-ray image. The x-ray image is then digitized using a Vidar scanner (570 dpi, 12 bit). After that, the image is inverted and partly colored using Photoshop, and the result of that you can see yourselves!

"It all starts with the availability of an animal. When I find an animal I start collecting attributes (plants, flowers, etc.). Next, I build the biorama. Then I do some radiation measurements and make some x-ray tests to find the optimal x-ray technique (dose and energy). I estimate that the whole procedure from finding the animal to the partly colored x-ray takes about 2 full days."

The most challenging part of the creative process for Arie is making the composition. "Usually, I want to make a still life that looks realistic." The moment the artist really enjoys is when the negative comes out of the processing machine for the first time. "That's the very first time I see the scene in X-ray. I am delighted and relieved when I succeeded. Unfortunately, it has to be repeated regularly because a leg turns out to be positioned wrong (unnaturally), or something similar. Then I have one negative less. And analog silver bromide films are becoming scarce and expensive."

"I love nature. It is amazing to see on x-rays the complex, wonderful and functional anatomy of animals. And all the similarities. Look at the elbow, knee, etc. of a reptile, bird, etc. all the same as the human. They all have the same setup, the same building plan. Even the trachea of the snake shows a construction like mine. I hope the x-ray images will contribute to the interest in nature."

Arie's images were published in a children's book by Gottmer publishers in 2017. In 2021, his work was published in English by Greystone Kids, titled "Inside In", and in June 2022, a second book titled "Doorgelicht" was published in Dutch by KNNV publishers for a wide audience of all ages interested in nature. Arie's images will also be exhibited in the Natural History Museum in Rotterdam from November 2022 – February 2023.

When it comes to the future, Arie would be very happy if he could get some (small) exotic animals from the zoo, like a flamingo, cockatoo, meerkat, etc. to make some new images!
