ABSTRACT:
A method of recording an image of a scene onto cinematographic color film comprises forming a number of successive partial images through a single lens system onto each single frame of the film, the successive partial images being recorded in light of different characteristics, for example different colors. The film is projected using a conventional projector, and when viewed through appropriate filters, gives a stereo scopic effect. To get an optimum effect, the sequence in which the images are recorded should be appropriate to the predominant direction of horizontal movement in the scene. Accordingly in one form of the invention, each image is divided into a number of areas, each area in successive images being recorded in light of different characteristics, and each image having different areas recorded in light of different characteristics. In another form of the invention, two successive series of images are formed on each time, or on alternate frames, the first series of images being formed sequentially in the reverse order. Filter members for use in a film camera for carrying out the method are described.
