ABSTRACT OF THE DISCLOSURE In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by taking a series of two-dimensional views of an object field and pro- . jecting them in an enlarger onto lenticular print film. Adjustable-focus and fixed-focus cameras are provided for taking the two-dimensional views, either simultaneously or sequentially, in a manner which automatically accounts for the effect of variation of the camera-to-object distance on the configuration of the enlarger-lenticular print film system, thereby allowing the parameters of the enlarger-print film system to be held constant. The number of enlarging lenses employed may correspond to the number of two-dimensional views to be projected, by virtue of which the stereoscopic picture may be composed in a single projection step, or a single en- larging lens may be used to project the two-dimensional views in sequence. As another feature of the invention, substantially -1- uninterrupted and non-overlapping lineiform image bands of high image quality are formed on all areas of the lenticular film by scanning the projected images from each two-dimensional view over a predetermined distance along the photosensitive surface.
