Space over Time

The series 'Space Over Time' shows how an observed space changes over a certain period of time. Few of us know 'slit-scan cameras', but we've all seen the photo finish of a sprint or horse race. These photos are created with slit-scan cameras to clearly determine who crossed the finish line first:

How does a slit-scan camera work and how does it differ from conventional cameras? In a conventional analog camera, the shutter opens for a brief moment and the incident light exposes the film. The photo shows on the x-axis and on the y-axis a space dimension. The time dimension is not visible. In a slit-scan camera, the very narrow slit-shaped shutter is open for a longer period of time and during the opening time, the film is transported continuously behind the shutter. This way only a very small part of space is viewed through a small slit - this space section forms the y-axis of the photo. The x-axis of the photo is the time, because the film is transported during exposure continuously past the slit. This makes visible how the observed space changes over time. A reality that we can not perceive with our eyes. And this is the theme of this series: the 'visualization' of a reality that is undoubtedly

a reality, but we as humans can not perceive. Or in other words, what we can perceive with our sense organs is not necessarily "all and everything" - there are things that are real, even if we can not perceive them. For this series rotating objects are photographed (many thousand slit-scan photos of each object). The works shown here are

72 seconds each of a melon, a benjamin fig, a whole Italian meal consisting of a red onion, garlic, spaghetti, basil, and Parmesan and a bottle of water. This way, futuristic-looking works emerge

as if from another world, although they only show a reality  we as humans can not perceive.

This project started in 2015 at a flea market in New York City. I had some time left before my return flight to Berlin and bought the book "The Great 'Life' Photographers" at a flea market in Greenwich. It was not until several months later that I came across photographer George Silk in this book. In the 1960s, he did the finish photos for the US American tryouts track & field in Palo Alto - with a so-called "strip camera". After the competitions, he went home, it was Halloween, and took pictures of his familiy with the strip camera. I was fascinated by the photos and immediately started experimenting with this technology myself. I wanted to see and show the change of space over time x. I took the first pictures of a turning egg cup on the kitchen table. That looked promising and I could see where it could go. But it was a long way to the first good photo. I had to design and build my own electronic turntable, develop software to handle the huge amount of data and above all, I had to gain a lot of experience on which objects are suitable and which lighting is suitable. It was a long way, but it was worth the bumby ride. Small, low-resolution photos were made quickly, but for high-quality and especially large-sized fine art prints, it was a long way - but worth it.
