Advanced Photo System (APS) is a now discontinued film format for still photography first produced in 1996. It was marketed by Eastman Kodak under the brand name Advantix, by FujiFilm under the name Nexia, by AgfaPhoto under the name Futura and by Konica as Centuria. == Design == The film is 24 mm wide, and has three image formats: * H for "High Definition" (30.2 × 16.7 mm; aspect ratio 16:9; 4×7" print) * C for "Classic" (25.1 × 16.7 mm; aspect ratio 3:2; 4×6" print) * P for "Panoramic" (30.2 × 9.5 mm; aspect ratio 3:1; 4×11" print) The "C" and "P" formats are formed by cropping. The full image is recorded on the film, and an image recorded in one aspect ratio can be reprinted in another. The "C" format has an equivalent aspect ratio to a 135 film image. Most APS cameras (with the exception of some disposable cameras) can record all three formats; the format selection is indicated on the film by a series of exposed squares alongside the image area or recorded on the magnetic coating depending on the camera. In the absence of an operator-specified format, the machine printing an APS roll will use these indicators to determine the output format of each print. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Advanced Photo System」の詳細全文を読む スポンサード リンク
