Techniscope or 2-perf is a 35 mm motion picture camera film format introduced by Technicolor Italia in 1960.〔Konigsberg, Ira (1987). ''The Complete Film Dictionary'' Meridian / NAL Books p.372. ISBN 0-452-00980-4〕 The Techniscope format uses a two film-perforation negative pulldown per frame, instead of the standard four-perforation frame usually exposed in 35 mm film photography. Techniscope's 2.33:1 aspect ratio is easily cropped to the 2.39:1 widescreen ratio,〔NOTE: In 1970, the SMPTE revised the 2.35:1 aspect ratio to 2.39:1 (now known as 2.40:1), however, before standardization, most Techniscope films were photographed and released in the 2.35:1 aspect ratio〕 because it uses half the amount of 35 mm film stock ''and'' standard spherical lenses. Thus, Techniscope release prints are made by anamorphosizing and enlarging each frame by a factor of two. ==Techniscope-photographed films== (詳細はThe Pharaoh's Woman'', released 10 December 1960.〔—retrieved 2007-03-19〕 Given its considerable production cost but lesser image quality, Techniscope was primarily an alternative format used by low-budget film makers, mainly in the horror and western genres. Since the format originated in Italy, most Techniscope format films were European productions. In the U.S., Techniscope was used in the low-budget A.C. Lyles Westerns for Paramount Pictures, and Universal Studios briefly used it extensively in the mid to late 1960s. Producer Sid Pink recalled that unlike Europe, the American film studios were charged by the Technicolor company for using Techniscope in their film prints.〔p.194 Pink, Sidney ''So You Want to Make Movies: My Life as an Independent Film Producer'' Pineapple Press, 1989 〕 Regarding the diminished image quality, film reviewer Roger Ebert wrote about the film ''Counterpoint'' (1968): "The movie is shot in Techniscope, a process designed to give a wide-screen picture while saving film and avoiding payment of royalties to the patented processes like Panavision. In this film, as in 'Harry Frigg', Techniscope causes washed-out color and a loss of detail. Universal shouldn't be so cheap."〔(Roger Ebert, ''Chicago Sun-Times'' review for ''Counterpoint'' )〕 Recent films shot with 2-perf 35 mm "Techniscope" include ''I'm Yours'' (2012), ''Silver Linings Playbook'' (2012), and ''Argo'' (2012). 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「Techniscope」の詳細全文を読む スポンサード リンク
