Abstract
A photographic method and apparatus for producing a motion picture including moving a film unit in one direction and the optics system along an arcuate path generally laterally thereto so as to produce a plurality of images on the film unit. The camera utilizes means for intermittently moving the film unit, such as a film card, in a first direction with the image produced in sequence in a plurality of parallel, arcuate rows generally laterally of the first direction. Alternate rows of images are produced along a first lateral direction while intervening rows thereof are produced along a second lateral direction opposite to the first one.
