![]() ![]() These lenses continue to be used to this day, particularly in special effects units. Ultimately “Bausch & Lomb formula” “combined” lens designs incorporated both the “prime” lens and the anamorphic lens in one unit. Chrétien’s Hypergonars proved to have significant optical and operational defects, but Bausch & Lomb, Fox’s prime contractor for the production of these lenses, initially produced an improved “Chrétien-formula” adapter lens design, and subsequently produced a dramatically improved and patented “Bausch & Lomb formula” adapter lens design. Twentieth Century-Fox’s pre-production of The Robe, originally committed to Technicolor Three-Strip origination, was halted so that the film could be changed to a CinemaScope production. Fox further purchased the existing Hypergonars from Chrétien and after some test screenings, Fox gave their go for further widescreen developments, which later became known as CinemaScope. The optical company Bausch & Lomb was asked to produce a prototype anamorophic lens. Herbert Brag then remembered the work by Henri Chrétien. ![]() Fox’s research department was advised to find a new projection system at modest cost. However, Spyros Skouras, the head of Twentieth Century-Fox, that technical innovation could help to meet the challenge. In the 1950s, cinema got a new competitor: television. Usually, however, a single optical element of this kind is not sufficient, since the sharp image planes for both the horizontal and vertical planes must both lie in the film plane. Thus the optically generated image is stretched or compressed in one direction relative to the other. The Anamorphic PhotographĪn anamorphic photograph consists of at least three cylindrical lenses, two cylindrical mirrors or a prism system. They represent a Galilean telescope for one of the axes. The recording of an anamorphic image: 1) object to be recorded 2) negative cylindrical lens 3) positive cylindrical lens 4) spherical objective 5) recording film 2) and 3) represent an afocal system, their focal lines are superimposed. The optical system called Hypergonar, which compressed and dilated the image laterally. With the help of an optical system that produces different magnifications in two directions perpendicular to each other, a distorted image is created, which is called anamorphic. Back then, Chrétien employed an optical trick which produced an image twice as wide as those that were being produced with conventional lenses. The basis for CinemaScope was probably formed by the French inventor Henri Chrétien who developed and patented a film process that he called Anamorphoscope in 1926. The film marked the beginning of the modern anamorphic format in both principal photography and movie projection. Like other early CinemaScope films, The Robe was shot with Henri Chrétien’s original Hypergonar anamorphic lenses. On September 16, 1953, American Biblical epic film The Robe premiered, the very first film released in the widescreen process CinemaScope. A set of Master Anamorphics effectively becomes four different anamorphic lens sets, each suitable for different flaring requirements while maintaining the famously distortion-free optical performance.CinemaScope logo from The High and the Mighty (1954). By using the ARRI Master Anamorphic Toolkit, the front and rear glass elements can be exchanged with the regular Master Anamorphic elements in a matter of minutes, since each flare element is pre-aligned in a metal frame. The flare elements can be used individually or in combination to provide the lens with three additional looks for enriched on-set creativity. Each of the nine Master Anamorphic focal lengths has its own specific flare set, comprising easily replaceable front and rear glass elements with a special lens coating that encourages flaring, ghosting and veiling glare. The ARRI Master Anamorphic Flare Sets are highly versatile and economical accessories for the ARRI Master Anamorphic lens series.
