LASER_DRAWING#3
1. Projektionsbiennale  Bad Rothenfelde Germany

Installation: Salina, laser, cctv projection
The project was conceived for the salina in Bad Rothenfelde. The construction built in 1880 is 10 meters high and 420 meters long and thus the largest constructed salina in West Europe. The salty brine pours over bundles of brushwood down into the depths and is thus swirled together with the air before landing in the reservoir. Two green crystal lasers (1000 mw) are mounted above the reservoir at a height of 6 meters parallel to the graded wall and at a distance of 50cm. The laser appears as an absolutely straight line and makes the movements of the tiniest particles visible against the saline wall. Over the course of around 380 meters, the following parameters change and, with them, the way the laser looks: distance of the laser beam to the graded wall (via the amorphous form of the graded wall/bundles of brushwood), divergence of the beam, light intensity and illuminated area. Over three months, the meteorological parameters will likewise greatly change the laser’s appearance: according to the weather conditions, dryness, humidity, rain, wind, fog, snow and ice will determine the brightness of the beam. A closed-circuit color video system records live a microscopic view of the laser: the extremely humid air, pervaded by floating white salt crystals, directly against the backdrop of the saline wall. Swirling drops of water, salt crystals, dust, insects and other tiny particles are recorded in a microscopic camera frame and simultaneously enlarged to a format of 12 x 16 meters and projected onto the graded wall. Curated by Manfred Schneckenburger
