PURPOSE:To imprint a great quantity of a data consisting of clear character, numeral, simbol, etc., by applying a sensitizing agent to a part corresponding to a part to which a sensitizing agent of the surface of a film is not applied, on the reverse side of the film. CONSTITUTION:A sensitizing agent 8 is applied to a center part 5 of a surface 3 of a film 2, and on the other hand, sensitizing agents 9, 10 are applied to upper and lower both side end parts 6, 7, too, of a reverse side 4 of the film 2. To one or both of the upper and the lower side end parts of the reverse side of the film, photographing data such as a photographing condition, an explanatory sentence of an image of an object to be photographed, etc. are imprinted by using a suitable optical system such as an optical fiber, a lens system, a hologram, etc., and also a cord of electricity, etc. for communication, from data packs which are provided or attached onto the reverse side of an optical device, and also are installed to the outside of the optical device. The image of the object to be photographed and the photographing data are not brought to a double exposure, and also light from the reverse side is made incident directly on the sensitizing agent without passing through the thickness of the film, therefore, any image can be inserted very clearly. |
