I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.

    Heidelberg Castle

    the Heidelberg Castle is world-famous and famous for the romantic feelings it triggers. Anyone who comes to the city in spring or early summer enjoys a mild warmth and a light wind that flows through the Neckar Valley.

    In autumn, the winds that hits the photographer is icy cold and the facial masks that you have recently at hand are a welcome support in taking pictures. The warm colors of the following photographs deceive one of them.

    The warmth of the Neckar gives rise to considerable early mist during a cold night, which stretches over the trees to the south and west. The mists also reach the Heidelberg Castle, which subsequently appears a little more romantic and ruined.

    Dahlia, my love

    Dahlia, my love. Flowers that make us forget the burden of a moment. Photographed each of them alone and as a pair. I tested HighKey shots instead of HDR, in the background different white tones.

    The result did not leave me alone. Afterwards I wanted to try my hand at photographing a hen’s egg to study shades of different white (basically grey and yellow) tones. Unfortunately this did not happen today due to an emergency examination.

    Porphyry

    In our vicinity there is a quarry that shone over to us in the afternoon with its warm colors. Loading the car with the heavy photo equipment, I drove there to try a few shots. The grounds were not as welcoming a I had imagined. Concrete paths and many closed gates that hindered a free study of light conditions. A remarkable amount of people on the road, often with dogs.

    The quarry named Referenz was used to mine for quartz porphyry, a red stone similar to granite, either used for road construction or e.g. statues. One rock formation was outstanding, with trees on it and a warm and yellow surface.

    On a mountain north of river Neckar through Heidelberg that was used spiritually by different subsequent cultures, there is a ruin of the monastery St. Stephan, with an arch that has probably bee reconstructed. It was already pretty dark when I got there. For the following shot it took me 2 minutes exposure time and 2 more minutes for noise reduction. You don’t see it.

    The Heidelberg Castle is always a great sight. It was almost too late to find a balance between the decreasing daylight and the electrical illumination. Nevertheless, with a single 90s shot at ISO 400and f/8, the basis for this image, which is a kind of negative, was achieved. The dark Heidelberg Castle dominates the scene.

    Reflection II

    Most of what we do see with our eyes is a reflection. Any light from a bouquet of flowers is just reflection. Looking through a bottle shows beside reflection some refraction.  The only exception, where we don’t see reflected light is e.g. offered by an open fire or a light bulb. The sight of a star also shows direct light, which is usually subject to refraction due to the atmosphere.

    Our eyes seem to absorb the light when we see. In fact, they can also reflect the incident light. We know this phenomenon from cat images that we have mistakenly photographed with a flash light. 

    Sitting in front of me my right eye is on the viewers left side and the left eye is on its right side. The instrument uses a red and a green laser at a harmless energy dose.

    With different wave lengths of a laser an ophthalmologist is able to see different structures of the fundus and uses this property for diagnostic purposes. Looking at the green color only that stems from the green laser, the result is a monochrome image that shows vessels of the surface of the retina and smalls nerves joining the papilla.

    Looking at the red channel displaying the reflections of the red laser light, monochrome images show deep vessels behind the retina.

    Beside the medical point of view there is an aesthetic one, too. Dr. Gösele, to whom I owe these beautiful pictures, confirmed to me the impression of an astronomical night shot, which other viewers also feel. With a courageous crop you get there:

    This is how the central part of my sensor looks like when creating photographs or X-rays. My wife immediately urged me not to fall into a narcissistic trap ….

    Reflection

    The word „reflection“ has a double meaning. It describes the mental process of thinking and the physical process of mirroring.  In the German language the same sounding word is written in two different ways. Reflection meaning thinking in German language is written with an x (Reflexion).

    The image in a mirror or a reflection of a water surface makes us thinking. That’s a pleasant quality. So I got attracted by some leaves on a water surface of a fountain in the well preserved older part of Weinheim.

    These leaves showed a beauty of color and a sense of rest. They seem to float motionless and at the same time flow slowly with the water. This is an image of time.

    Chestnuts X-ray mammography photo

    I hav been looking forward to the mammography of these chestnuts a whole week. It was almost too late to find some specimen that had not yet been trampled or eaten. Once again it was helping hands that made this picture possible for me.

    It was difficult to get an attractive composition. Indeed some skills have to be developed to place the chestnuts – because they really hurt. The sensor was too small to x-ray the whole composition at once. The solution was a mosaic with two tiles.

    The result is convincing to me. The viewer may feel the thorns looking at the image.

    Loaf of bread

    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.

    Stages of a print

    „Print early – print often“: important advice given by Charles Cramer. With my battery of my Nikon empty we strolled along a cornfield. A broken corn cob  in a mature field suddenly caught my attention. The characteristic envelopes were partially peeled off. Red threads, which children use for playing as hair, hung tangled down. So I took my iPhone to get this image done.

    Beside the original with rogue disturbing lights I did some dodging and burning to enhance the print. This first step is the most important before getting into any other filtering process:

    Farewell

    With flowers we create feelings and express feelings. With flowers we want to elicit feelings. If they aren’t just a comfortable souvenir, that is not suitable for the wall or the shelf.

    Their color is not enough to stimulate our emotions. It’s also their shape and a composition.  I took a friend to my favorite florist to design a bouquet from the available flowers end of September. The central component were two specimens of a cockscomb, one in red and one in purple.

    A not insignificant part of the enjoyment is the creation of the composition, together with a sensitive florist. At home I photographed the bouquet with the horizontally aligned, rectangular Lightbox in the background. It’s, of course, an HDR image, combined of shots with the Lightbox switched on and off. A final greeting of the noticeably farewell summer.

    Farewell has always been a theme of flowers. Without color, subject only to the effect of light, exposing a feeling for the original color, the black-and-white image of a flower becomes intensified. The same day at sunset, with an exposure speed of 6 minutes at ISO 50, I obtained the following picture, which made me immediately think of The Godfather: I’ll make him an offer he can’t refuse.

    Gift

    It had take a long time until I had chosen a beautiful floral arrangement and d the florist had bound it presentably. I was just about to complete the purchase when I noticed a wonderful Gladiole.

    „I’ll give it to you for free of charge, it has already fully blossomed“, said the owner. My thanks to her are the following pictures of this flower, which I made with my lightbox in the background.
