Analogue, yet virtual The first approaches to the world of stereo shadows were entirely analogue, involving experiments with shadow projections. Since then, numerous works have been created in which stereographic shadows are captured directly on light-sensitive material, similar to an X-ray picture.

Polaroid series (since 2015) The instant photo series shows that exposure with a red and blue light source does not necessarily have to be simulated on a computer, but can also be achieved in analogue form using relatively simple means. Depending on the viewer's eye, it takes a little time for the 3D effect to kick in with these unique pieces. While the effect only works in one direction with camera-based stereophotography, it is variable with stereo shadows depending on how the picture is hung. Sometimes the space flips backwards, and if you turn the picture upside down, the space flips forwards.

Toile d'araignée (2019) Even Christian Schad had to wait for the night to fall to create his late Schadographs in darkness. The work Toile d'Araignée is also such a "night picture", created only after nightfall in the cellar of a century-old house. Over decades, a large spider's web (French: toile d'araignée) grew there, its fine threads proving to be true dust collectors. An intricate web of threads, around two metres deep, is compressed spatially in the backlit large-format slide, which was originally captured on colour sheet film.
