Thomas Kellner has been making his unique style of mural-size constructions of 35mm contact prints for many years. He's perfected a technique that requires each frame of each roll of 35 mm color film to precisely record a tiny segment of the larger whole. And then, working within this rigorous system, he plays a bit with tilted angles and repeated images.

Recently, he was commissioned to document some historical industrial buildings in Russia and Germany. Here are samples of some images from that project, as well as some background information from Kellner:

This project deals in an artistic-photographical manner with two important industrial areas in Germany and Russia, which are linked to each other through the common history of industrial culture. I’m talking of my hometown Siegen and two of the biggest cities of Russia, Yekaterinburg and Perm.

Yekaterinburg and Perm were founded by the native of Siegen, Georg Wilhelm Henning (1676 -1750). He was  invited by Peter the Great to Russia because of having an outstanding knowledge in metallurgy. In the 1720s he founded the first mining schools in Russia, travelled to Europe to promote specialists in mining and built new plants in the Urals, which developed in a minimum of time to become one of the most important economic and educational centers.

In 2013 I followed the traces of Henning and photographed important enterprises in Germany and Russia to show their similarity, namely the processing of steel and metal. As result there emerged a series about the industrial architecture in the Siegerland and the Urals, that presents the heretofore little known relation between these industrial areas. 

The Russian photography curator and author Irina Chmyrewa writes, "Architecture is similar to a full stop which completes the artistic process. Yet at the same time it is the starting point for the observer's new artistic journey — that is what Kellner does."
