Integrated process for three-dimensional taking, copying and reproducing of still and moving pictures, in which (a) the taking of still or moving three-dimensional pictures is done using conventional cameras which expose as many two-dimensional pictures as there are cameras, there are n cameras which are distributed in groups or supergroups, there being inserted between each two horizontal camera groups which have their optical axes mutually perpendicular a semitransparent plate forming 45° with the groups, the optical axis of a camera remaining situated in such a way that its projection remains at the mid-point between optical axes of two adjacent cameras of the other conjugated group; the undesired rays are suppressed using a completely black plate; (b) in order to copy the n pictures taken, the latter are grouped together in trios, the left and right pictures being copied in a specularly inverted state with respect to the central picture, each one of the trios being situated at a different projection height; (c) the projection is performed using n/3 projection lenses, adjusting these lenses in such a way that the central picture of the film is reproduced directly onto the transparent reproduction screen or through a front reflection by a reflecting mirror situated in front of the lenses; the lateral pictures being projected via reflections in systems of lateral mirrors; and each one of the n/3 projection lenses is situated offset in height with respect to the adjacent lenses.
