摘要
The method is to make a multicoloured backing sheet. A fixed screen (1) is placed in front of the objective of a camera for taking colour shots. Out of the camera line of sight are placed at least two lamps (4,5), of different colours. In front of each lamp is placed a tube (6,7) with the free ends of the tube pointed at the screen, which is tinted to the lamp colour. The tubes are arranged so that the colour of a chosen zone has fringes of each illumination overlapping. The tube shapes can be varied.
