CinemaScope - Technical Difficulties

Technical Difficulties

Although CinemaScope was capable of producing a 2.66:1 image, the addition of magnetic sound tracks for multi-channel sound reduced this to 2.55:1.

The fact that the image was expanded horizontally when projected meant that there could be visible graininess and brightness problems. To combat this, larger film formats were developed (initially a too-costly 55 mm for Carousel and The King and I) and then abandoned (both films were eventually reduction printed at 35 mm, although the aspect ratio was kept at 2.55:1). Later Fox re-released The King and I in the 65/70 mm format. The initial problems with grain and brightness were eventually reduced thanks to improvements in film stock and lenses.

The CinemaScope lenses were optically flawed, however, by the fixed anamorphic element, which caused the anamorphic effect to gradually drop off as objects approached closer to the lens. The effect was that close-ups would slightly overstretch an actor's face, a problem that soon became referred to as "the mumps." This problem was avoided at first by composing wider shots, but as anamorphic technology lost its novelty, directors and cinematographers sought compositional freedom from these limitations. Issues with the lenses also made it difficult to photograph animation using the CinemaScope process. Nevertheless, many animated short films and a few features were filmed in CinemaScope during the 1950s, including Walt Disney's Lady and the Tramp (1955).
