摘要

Production of picture, by partial removal of color in layers from cut-out pieces of photographs assembled in collage or mosaic. A picture can be made from a collage of cut-out pieces of photographs produced by four-color printing by removing layers of the color with the aid of a sodium hypochlorite (20 - 40 g/l) or bleach solution applied for 1 - 10 seconds by means of a brush, pen or cotton bud. The application of the solution removes colors one at a time, and the process is stopped by rapid absorption with blotting paper. When a picture has been produced it can be finished with ink of an acrylic resin.
