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.
Claims3
A method of producing motion pictures comprising the steps of:
- supporting a sheet of photographic film in a given film plane;
- intermittently directing scene light from a photographic scene to spaced areas of said film plane to produce images thereat, said directing step including directing scene light along a first path generally parallel to said film plane and then along a second path generally normal thereto;
- pivoting said first path around an axis spaced from said second path and generally normal to said film plane to produce an arcuate row of images in said film sheet;
- advancing said film sheet, at the completion of each said arcuate row, in a direction substantially normal to said arcuate path to provide an unexposed film portion in said spaced areas;
- and
- repeating said directing and advancing steps to record a plurality of image rows in said film sheet.
