A picture is a section between two transformations , i.e. changes of decoration, during which the curtain usually remains closed. The scenery does not change significantly during a picture . Depending on the frequency of the transformations, an image can sometimes contain an act and sometimes a scene. Usually it consists of several scenes. In the case of unit decorations, one image encompasses the entire theater performance.
Until the 19th century, this picture consisted mainly of a painted stage prospect in the background, which only had to be changed by pulling cables. When the decorations became more elaborate, for example with trees or furniture on the stage (see naturalism (theater) ), hosts of stage technicians were busy changing the image. - Today, differentiated theater lighting often saves the need to renovate.
