​"The Followers demonstrates von Zwehl’s most radical use of the silhouette [to date]. In this series, any resemblance to a portrait has been abandoned in favour of abstract shapes. Produced without a camera or negatives, these works use, the traditional analogue process of wet tray printing, where a sheet of photographic paper is exposed to the light, and then developed and fixed in the dark - altering the process by crumpling, folding and tearing at the fragments of paper while they were in the chemical trays, and then drying them before subjecting them to the same wetting, folding, crumpling and tearing.
The resulting images, due to their flatness, can be read as elements of an obscure code or language system. Alternatively, they resemble prehistoric rock fragments worn away, chipped, and broken over millennia. They also function as crude representations of humans. "
