This artwork is a photogram, exposed directly to black and white Fomapan photographic PE paper, using a modified color CRT-tube. The cathode ray (stream of high energy electrons) is controlled by electronic sound waves, drawing the forms and patterns of the images. The ray passes through a tilted lens, creating variation in the sharpness of the images. The visible range is actually the color-separation grid inside the used CRT-tube. The photographic paper is then hand developed in large baths to enable broad black and white dynamics. Is a unique original piece, since it is impossible to reproduce, due the technique used for making it. An attempt to re-trap the same sound, would produce a different result.
