ABSTRACT:
A 35 mm-wide photographic film without any perforations typically used to transport this kind of film has one side of its rectangular effective photographic area in a widthwise direction made substantially 30 mm long, thereby widening this effective photographic area, so that the image quality is improved. A photographic camera using that 35 mm photographic film formed without perforations transports the photographic film accurately, and in which the position of the photographic film in its widthwise direction is defined and an image of an object is exposed to the effective photographic area of the photographic film.
