Abstract
Standard film packages and telephoto-type film packages and panoramic film packages are produced using the same standardized package bodies which are adapted to photograph full-size frames on 35-mm film. In the factory, each package body is loaded with a photographic film, and indicia of the type of the film package to be produced are provided on the photographic film or a cassette for containing the photographic film, as well as on the film package. When printing a photographic film having been loaded into such a standard film package, substantially the whole area of the full-size frame is printed to make a standard print, whereas printing of photographic films that have been loaded into the telephoto-type film package and the panoramic-type film package is performed such that only a partial area of the full-size frame is printed at different print magnifications which are larger than that used for standard prints. The fields of view in the viewfinders of the telephoto-type film package and the panoramic film package are changed from that of the standard film package, so as to correspond to the respective areas to be printed for making telephoto prints and panoramic prints.
