My conference schedule allowed me a walk through the Berlin Tiergarten Park in the morning. Of course, with a cam handy. While I was sitting on the shore of the Landwehr Canal, I let myself be carried away by the waves.
The waves made the reflections of the trees and bushes softly tremble. The resulting reflections became like paintings.
The processing was carried out only with regard to brightness and colors. Lab colors were used. Light-dark-contrasts were given by the waves.
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.
Camaret-sur-Mer is a place with a long history, which tells the former economic and military importance. Cabaret has been also the most important lobster port in France. The place is located on a peninsula of strategic importance for the security of Brest. The peninsula was therefore coveted by Great Britain and Spain in their fight against France.
The Vauban tower bears witness to France’s fight against the conquerors. I took the following image with my tripod in front an old warehouse of the former shipyard.
The civil shipwrecks show the decline of fishing in the region. You can’t find warships here.
All ships are damaged, by time, by economic ruin. This is where they found their last port.
Where is our final anchor point ? Will it be interesting to look at us ?
Second journey to Leipzig. Half way stop at Schloss Seehof in Memmelsdorf. Finest square architecture. Splendid water cascade.
Leipzig has been a town since round about 1200. Many places were reconstructed after destruction during socialist dictatorship. The horrible blast of the Pauliner Church in 1967 lead to a beautiful and appealing reconstruction after 1989.
Karl Blossfeldt was a German photographer who lived from 1865 to 1932. He didn’t think himself a photographer. With his studies of plant forms he made an enormous contribution to plant photography. Here is a nice wikipedia article about him.
He started to do photograms. Plants or parts of plants were placed directly on film or paper suitable for exposure. Exposure then takes place without any optics. Later he built himself a wooden camera, which reminds me of Andreas Feininger.
Black and white backlit macro images with a background can be similar to Blossfeldt’s images.
You never know in advance what it means to return to the place of childhood. On top of a 217m high television tower physically overlooking the years I spent near a forest in Stuttgart Gablenberg there was a feeling of returning or being at home.
A few memories to the first visit to this tower mixed with the fantastic view. My daughters had invited me to this evening as their birthday present to me. The waiter is friendly and brings us as a special exception a white tablecloth to celebrate the day. So it’s fun to get to know the carefreeness.
We enjoy delicious local food while the sun is getting lower and lower. Occasionally I feel a touch of fear of heights. Our table stands directly at the window with a view of the city.
Nevertheless, we go up to the higher viewing platforms to look and take pictures. Suddenly many other photographers appear out of nowhere and we take many pictures of the view and a spectacular sunset.
It’s still light when we left. The landmark of the city can be photographed in a variety of compositions. Here is just one of my many:
Every camera stores sensor image data in a file for further use. The sensor image data are just grey values of different intensities in every pixel. A single pixel doesn’t show color. Our sensor image data contain a black and white world. How sad.
How do we get color images with a sensor that maps only grey values between white and black ?
All the colors we know can be derived from a combination of a specific value of Red, a specific value of Green and a specific value of Blue. If we know the shares of Red, Green and Blue in a color we know the color.
Our camera sensor measures the shares of Red, Green and Blue with small lenses in front of each pixel on the sensor that act as filters for Red, Green or Blue. The complete sample of these filter lenses is called a color filter array or „CFA“. The distribution of Red, Green and Blue filter lenses on the sensor is completely known only to the manufacturer.
The file that contains the sensor image data is called a RAW file. Beside the sensor image data at the beginning of a RAW file are informations about the complete file content. I found a nice Wikipedia article pointing this out. A RAW files contains also exposure data and information about the camera lens.
A software converting the sensor image data of a RAW file into pleasing colorful images is called a RAW converter. A well known and popular RAW converter is Adobe Camera RAW (ACR). A Phase One Raw file can be straight forward converted by ACR to a 16-bit TIFF. No further postproduction has been applied (see left image below).
A RAW conversion of the same file with the Phase One manufacturer’s own RAW converter Capture One to a 16-bit TIFF shows different color and brightness (see right image below). There was no setting of temperature, hue and saturation to make the images identical.
One RAW file was converted to two different TIFF. The difference between the TIFF can easily be obtained in Photoshop with the difference layer mode. The difference is an image in itself. With a sensitive gradient applied the following image is obtained:
The difference TIFF (Capture One) – TIFF (ACR) is derived pixel by pixel. The converted TIFF using Capture One contains more green, more magenta and more yellow in the darker values. The impact on the final result is unclear at the moment.
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.
Just normal light of our living room let me to a nice coloring and interesting shapes. The blossom next to the lower right corner is a Siamese twin on a double stalk.
There are many stops put to a CT-scan, especially when dealing with women in reproductive age. We are always very careful before exposing any patient to radiation.
This middle-aged patient with repeatedly nausea and discomfort opposing pregnancy very strict and claiming menstruation 28 days ago underwent some medical examinations including gastroscopy and, eventually, a CT-scan.
We were prepared for a tumor when scanning the abdomen. We were amazed to find a baby despite many questions about patient’s history before the exam. Maybe, some obesity covered the situation with a veil.
You can see the bones of the upper and lower extremities, as well as the skull and some parts of the spine. The ossification of knees, feet and hands will take place the next ten years after birth.
It appears to be discussion-worthy if it’s a boy. Our methods didn’t lead us further on this.
To me the rotated, inverted and cropped image resembles to cave paintings. These paintings are assumed to be some kind of religious art, reflecting astonishment and grandeur of lost civilizations.
Certain is, the baby touches its right ear, as it was amazed by itself or reflecting its life. What else than human life is this ?
I like organ music. And I like the architecture of an organ. It’s always a composition of different metals and woods.
Today my favorite organ player gave us nice preludes as a present during the service.
