Program material in the form of a slide show composed of a sound material and a picture material in the nature of still pictures comprises a general picture-material part which is relevant to a plurality of presentation occasions and a specific picture-material part which is relevant to solely one or a few number of presentation occasions. The program material is presented by showing a film recording of the general picture-material part, whereas the specific picture-material part is shown in the form of diapositive picture slides. When producing such program material, a corresponding slide show is filmed in its entirety and the areas of the film corresponding to the specific picture-material part are provided with neutral or dark parts such as to form a picture-free area of the picture field (5) of a film projector (2) on a presentation surface (1) when showing the film, within which area the diapositive slides can be projected. |
