White Noise pictures are made of the noise of the Bamboo forest and the white light of the day. This is an approach to translate the sound of the wind, to repeat the meditation I unwillingly underwent when nothing could catch my eye except the repetitive movement of trunks and leaves.
Through your sleepiness one of those old challenges emerges — how to draw the music? how to photograph the sound?
