Technical production of 35 mm film deformation widescreen

1927, French physicist Henri Jacques Chretien developed an anamorphic lens, which can deform the image laterally and widen the image. This is CinemaScope widescreen technology, which can produce special effects and lay a technical foundation for the birth of widescreen movies. 1952, 20th Century Fox Company of the United States first realized the importance of this lens, so it bought a patent and applied this technology to film shooting. When shooting, a special anamorphic lens was used to compress the panoramic picture of 2.35: 1 onto the 35mm film of 1.33: 1. When showing the shot film, a morphing lens is added to deform the picture in the opposite direction, thus restoring the picture. This is the basic method of making and showing wide-screen movies. 1953, Fox used this technology to shoot the first wide-screen film "The Robe", which was so successful that cinemas began to install new wide-screen deformable lenses on projectors. Within a year, CinemaScope technology and its four-channel stereo were adopted in major cinemas. By 1957, 85% cinemas in the United States had installed CinemaScope technology equipment. There were other widescreen formats in this period, many of which used 70mm film to improve the image quality. Although more than 900 screens are equipped with 70mm film projection equipment, this format is rarely used. Some unique people still use this format, mainly for sound. 1997 James Cameron's Titanic was the last 70mm film released by major film companies, but it was still shot on 35mm film, and only 70mm was used for distribution. Wide-screen movies broaden people's horizons, so they are especially suitable for showing magnificent movie pictures. Nowadays, widescreen movies have been widely adopted by countries all over the world.
