Technical notes on the camera obscura:


• The LENS of the camera was custom built: It is an achromatic Doublet lens with 6 inches diameter and 102 inches focal length (f/17). The lens is fully coated to reduce reflections.


• The CAMERA was built under strict specifications to meet both public access codes and the needs of the artistic project which require the camera to be portable (able to be re-installed in different sites), large enough to accommodate as many as 25 people at a time.


• Our eyes naturally see things upside down; it is our brain that processes the image "right side up".


• Revealed Portfolio 1.0 consists of 22 photographs


• Revealed portfolio photos are archival pigment ink prints and measure 24" X 24"


• Portfolio 1.0 was created with a Hasselblad H2 camera with a 22 MP Leaf back, June, 2006.


A special portfolio of high quality photographic prints have been created using this camera obscura and featuring images from the site-specific performance. For information on viewing and purchasing these prints, please contact Stephan Koplowitz at

Kohler Körper is a site-specific work inspired by the physical design of the Kokerei Factory; it’s mission, purpose and history.


The work is divided into three sections requiring the audience to promenade to different locations during the performance.


Part ONE: One the roof of the factory in front of the coke ovens: this section features 22 dancers who are placed in front of the metal structures.

Part TWO: Down the stairs inside the factory on level one: This section features 42 dancers divided into three groups of 14.


Part THREE: When section two has ended, the audience is asked to make their way to the front of the factory to view all 50 performers on various levels of the building.

Neurotic movement patterns amongst the coke ovens speak of human powerlessness. No less oppressive is the tableau in the second section: The viewer looks down on the dancers, in a 50-meter-long groove like mice in the cage, witnessing their vain endeavor to surmount the incline plane to climb, escape out - a contemporary Sisyphus myth in strong images, helped by the effective but unobtrusive lighting design by Simon Corder. A gigantic space adventure was finally in the third section, where the dancers are placed high above the audience on lighted walkways and exceeded the entire outer wall of the complex Zollverein factory, like a temple brought back to life. And they even turned the Ferris wheel. A remarkable thing.

Mensch, Arbeit und Maschine,  Getanztes Kokerei-Projekt in Essen  

Von KLAUS ALBRECHT, September, 1999


In the context of this distinctive venue, (Koplowitz’s) movements were interesting and arresting right the waythrough to the end. It really doesn’t matter whether one views the Kokerei-Project as aperformance or a ”Son et Lumière“ event because, after all, the intention is to throw light on thebuilding, its magnificent construction, morbid charm and deserted romanticism.
