Luminograf #1 is a machine that exposes light- sensitive surfaces.
It consists mainly of a discarded CD player that has been disassembled and put together in a new way to transform its original functionality.
The machine’s center section contains a laser diode that inscribes traces in photosensitive paper.
It performs simple motion algorithms executed by a connected mini-computer.
These computer signals mix with mechanical inaccuracies of the collage-like construction.
The resulting interferences lead to complex and unpredictable movement patterns.
The actual exposure process is visualized by a video clip.
It shows Luminograf #1 exposing a phosphorescent film instead of photosensitive paper.
In this case, the interplay between analog “error” and digital instruction is represented by a constantly changing arrangement of temporarily illuminated dots.
The laser diode exposes a random spot on the phosphorescent film whenever the machine is blocked.
Static black and white prints are developed in the darkroom.
They show the results of experiments with different physical and digital parameters.
Enlargements of wider resolution are reminiscent of landscapes that enable a physical experience of the invisible.
