4 bars of chocolate were meant as a reward for a calendar of the year 2023. To eat, of course. However, it is a special pleasure to subject them to an X-ray examination with the mammography before opening them. After three attempts, I placed them on top of each other, which is why their penetration with radiation required 20% more energy so that the image was not underexposed.
What happens to green leaves when I turn them into black and white? Again and again I photographed ferns. During a hike in the Black Forest I photographed groups of different leaves with different shades of green and brightness.
The result was clear to me beforehand. I had found such an idea in the images of Ansel Adams.
Less subtle is the following motif with a wooden bench for tired hikers. In this image the fern, the bench and the stone marker are the brightest objects.
Different hues of green lead to different levels of brightness in the black and white cosmos. Our destination for the day was Lake Buhlbach, which unfortunately could no longer be circumnavigated on foot in the newly opened national park.
The basic question of the creative photographer is, wether the representation of a photograph is literal or a departure from reality as projected in his „mind’s eye“. An expressive image is photographer’s goal. When the interaction of the different factors of exposure, aperture and camera characteristics is well understood, creative freedom knows no limits. Positively speaking: the sky is the limit.
The scenario of an almost threatening thunderstorm cloud, which, however, is still in a protective distance, is sometimes surprising on the beach. The tetrapods on my image will protect the island from flooding, but not us from rain.
A colored picture blurs this impression completely. Black and white rendering clearly shows the energy inherent in a thundercloud. We came across this cloud at Hörnum and it accompanied us all along the beach.
Just a short time before, I managed to capture the impression of a constantly beautiful weather with a cool wind and gentle waves. A strong sun pushes away all dark thoughts. On the horizon, the clouds are raining a bit.
Many times we are waiting. We like to draw strength from contemplation. Time is passing by imperceptibly, almost a little too fast.
With color photos expressive images can also be created. The true brightness values of a color image like to deceive our eyes. Quantitative estimation with the help of Lab color display is a great help in the accurate determination of brightness values. To make an image look like I had it in my „mind’s eye“.
An idea of Ansel Adams regarding the reality of a photo keeps me captive. His best photos, as he writes in hisbook “The Negative”, are often described by viewers as truly realistic. But they’re not. On the contrary. These would often have been the most intensively worked on by him.
He repeatedly insists in this book that the best images would have been those in which he left reality in the processing to show what he wanted to show or felt.
I am often impressed by the clouds passing by or the play of clouds in the sky. In a colored picture, I don’t quite succeed in directing the weight of the picture to the clouds in the sky. Despite the use of filters with and without gradients, the color image is beautifully colored and bright, but the desired focus is lost. With black and white pictures, it seems to be easier.
I wanted to study shadows of simple bodies again today. It all started with an egg last week. The shadow of last week’s egg photo was ring-shaped. I noticed that, but it didn’t bother me. Could the ring shape of the shadow be overcome by skillful selection of light and would the backside of the egg lie entirely in the shadow? This assignment was given to me by a school friend, who himself is a professional photographer.
The shadow looks better today, with a little help from Photoshop.
A neighbor had given me simple bodies, which I placed like an egg on the white background. First of all as a play with form and shadow, where I had to think of the X-ra image of a human hand.
The small wooden blocks were wonderfully colorful. Unfortunately, I didn’t have as many as my imagination would have liked. Arranged in concentric circles, they are delightful to the eyes. At the suggestion of a friend, I arranged, the number of blocks into Fibonacci numbers. The processing of the shadows leads to an exciting image, similar to solarization. Since it is a kind of negative, I named the picture after the impression it makes: „Flow of light“, although in reality it was the shadows of the blocks.
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.
It is always overwhelming to be on the road in Yosemite Valley. One is welcomed by silence and forest air. One of the points that provide an easily accessible overview is the former parking area for road construction machinery at the tunnel to the south: Tunnel View.
Everything slows down when you dive in there. The modern distractions are eliminated. The internet connectivity is so slow that you can’t present your pictures to anyone else while you are there. It’s a pity for those being at home.
Native americans lived in this valley and were given plenty of water. That has changed in the meantime. Precipitation is missing. An endangered jewel of this earth. It was a privilege to have been there with a friend and to be allowed to take pictures
Our universe has to some extent a structure like a foam. How to image this ? Computer simulations did already some successful representations.
Doing X-rays on a freshly baked loaf of bread I got some features of a foam. My loaf was bigger than my X-ray sensor, so I had to stitch two tiles. Photoshop did a really good job to merge the X-rays.
The image looks more like a interstellar object than a loaf of bread.
This Monday arrived my new oranges from Valencia, Spain. They are sweet, juicy and just delicious. I shared half of the delivery with my employees who had also been waiting for it for a long time. We eat or drink them. Some were x-rayed for artistic reasons.
There is already a routine in doing these X-rays with food. But sometimes an X-ray machine has a life of its own. The first images are taken to check the exposure before we venture into a composition. The aperture of the X-ray tube may become narrower and unwanted images like the following may be produced.
This image was created by playing with textures and colours:
You can easily imagine a stack of oranges with the fruit lying on top of each other. The perspective of this X-ray image is from above, so that the effect of translucency is created. Because of the triangular arrangement of the oranges, one would think that the apex of the triangle would indicate at the top. In fact, the center of the triangle is at the top.
Has the future ever been read from the migration of the clouds ? Their forms and movements have always been exciting and inspiring for me. A vortex of clouds immediately creates a vortex of emotions.
That is why clouds have long been the subject of my photographic interest and I have created a considerable collection of cloud images.
Last night a long heat wave ended with a thunderstorm. Above our house the clouds were swirling, lightning sometimes closer, sometimes further away. Islands of brightness changed rapidly in a threatening sea of black clouds.
In some ways, these clouds remind me of interstellar gas clouds in our galaxy. In the example below the colors of the panorama image of M8 (or „Lagoon Nebula“) are suppressed to better recognize the structure.
