Remarques

Marque : "Varamorph. Sole distributors GB-Kalee Ltd London. Made in England. Magnification 1.38 1.5 2".

"My first experience of prismatic anamorphic attachments came when I joined the BBC at Ealing Studios as a trainee projectionist. The 35 mm preview theatres were equipped with GB-Kalee 21s, complete with Taylor-Hobson Varamorphs. As the name suggests, the expansion ratio could be changed by operating a knob on top, connected to pivots which changed the relative angle between the prisms. At the time, in 1963, this seemed to be a superfluous feature, as all the anamorphic prints we showed had the same x2 compression ratio, whatever widescreen process had been used to photograph the film. However, back in 1954, when the Varamorph was first introduced, there was the possibility that prints would be available with a different amount of squeeze to that of CinemaScope's x2" (Grant Lobban, "Fun with Varamorph", Cinema technology, march 2008, p. 55).
