I am interested in the dark room, the darkness, the night as an amplifyer for the audio-visual sensation under rather limited circumstances.
I am also dealing with the dark room as a projection area for inner conditions - let´s say in the head room and body room - may they be of phsychological origin (like fragments of thoughts, barrages of images, monsters, anxiety) or of physiological nature like variuos optical illusions in darkness and in the transitional state from wakefulness to sleep (like phosphenes, exploding head syndrom, prisoner´s cinema). Same for the acoustic perception.
For the technical implementation of the recording of sound and video several dark rooms have been set up as an audio-visual apparatus:
two video projectors threw abstract images (generated by the sound in the room) into the pitch dark room where several light-sensoric devices catched beams and flashes of the light of the projections and so either triggered little motors that where placed all over the room or computer generated sound samples. This room - sound was again feeded into the video generating tools (analogue video mixing desk, synchronator). The sound was recorded with several microphones throughout the room, the light and image projections in the room was recorded with a camera. no effects, additional imagery or sound added in the process of editing & assembling.
