It is a not too short distance from Arnarstapi to the Güllfoss in the heart of Iceland. The constantly changing weather is a stroke of luck, as are the long days. As a driver of a car, my pleasure increases with leisurely speed and music appropriate to the landscape.
Detlef and I have been going on astronomical adventures in different combinations for 10 years now. This time we’re going on our own for the first time.
Modern cars allow you to bring your own music with you via your mobile phone. This way we discover our preferred composers and musicians have a broad commonality.
Today it is Arvo Pärt’s turn, which has written music that could be taken to a planet that is still uninhabited or sparsely populated. This fits perfectly with the early plant settlements on the volcanic rock and the April weather of the island. With Arvo Pärt’s music, the rugged features of Iceland disappear and turn into gentle forms.
On the way to the hotel at the Güllfoss waterfall we come across Strokkur, a reliable geyser with the same blue colour of the water when it starts to rise driven by steam.
Shades of grey in interaction with light: this is a theme for monochromatic images. For a long time I wanted to photograph an egg against a white background. The idea was stimulated by photos, mostly of people I know personally. Geometric, white-colored bodies from the mathematical collection would also be fun for me. Unfortunately, access is not as easy for me as with an egg.
On the left side the egg is brighter than the background, on the right side it is the other way round. The background itself loses a little brightness from the left to the right, but is brighter than the the egg on the right. The contrast changes. There is no clearly defined shadow for this setup. The same is true in the next photograph.
With the help of a simple light source whose color temperature does not matter after conversion into a black and white image, a soft shadow can be achieved if the source is not point-shaped.
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.
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 !
Explanation of the idea
Fusion imaging is a child of the digital era of mapping structures. Before image fusion was used in diagnostic radiology, astronomers used it to extract new insights from our universe. Fusion imaging of flowers can be beautiful. And, maybe, it’s a starting point for research in new fields.
The use of photography was initially, after its invention in the 40s of the 19th century, nothing more than a gadget. Only by astronomers, that used used photography for detection of asteroids, photography became a serious matter. By comparison („blinking“) of photographies astronomers discovered mobile objects within a field of fixed stars. In Heidelberg, Max Wolf (1863 – 1932) has been a pioneer of astrophotography.
Imaging of flowers is nothing new. But in the digital era of photography, the mapping possibilities changed fundamentally. It became possible to create the illusion of transparency or translucency by using a set of HDR images at the HighKey side of the exposures. The procedure was introduced by Harold Davis.
X-rays were initially used for medical diagnostics and therapy. Their ability to reveal structures inside an object with an opaque surface was the driving feature of technical development in this field. Nowadays x-rays are used to examin technical structures and there are telescopes to map x-rays from our Galaxy. Every technician who started in its profession learned to do x-rays of interesting structures like flowers, animals or teddy bears. X-ray images of flowers are nothing new.
Transparent looking flowers and transparent looking x-rays of the same flowers are each already for itself appealing to our eye and mind. By combining two digital images of the same structure in visible light and x-ray there is something new to happen. We name this combined procedure „fusion imaging“ and the result of a combination a „fusion image“.
