ABSTRACT:
A camera includes a film metering mechanism that controls longitudinal movement of the film for half-frame exposures. Film movement alternates between a first distance and a second distance greater than the first distance. The first distance defines abutting pairs of exposure frames and the second distance defines a space between adjacent frame pairs. According to more specific features, film movement is controlled by a cam that includes a first section defining the first distance and a second longer section defining the second distance. Still more specifically, the cam is circular, is driven by the film movement, and includes opposed asymmetric lobes, one for the first distance and the other for the second distance. Each frame pair defines a size equal to a standard 35 mm exposure, and the space between pairs also equals the 35 mm standard. The paired frames can be printed in standard equipment without special handling or procedures.
