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.
There is also a version in Black ad White and a color version of this photo.

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