I've just put on my anorak .......
A real CinemaScope film was shot onto 35 mm neg with the anamorphic lens on the camera providing the 2:1 'squeeze'
I knew there was something unusual about Carousel, so I looked at imdb -
it was shot 'flat' onto 55mm neg, and the 'squeeze' done in the printing process, presumably at the'inter-neg' stage
[it was tri-pack (color by DeLuxe) rather than 3-strip Technicolor ... both 'DeLuxe' and 'CinemaScope' were (c) C20th-Fox].
The 35mm release prints were stretched by the anamorph on the projector -
the 35mm twin-lens machines used a half width raster to scan half the frame and thus un-stretch the squeezed picture,
'pan and scan' (although we never called it that) determined which horizontal part of the frame was scanned;
the 35mm polygons (at Lime Grove) did the reverse, they removed the 'squeeze' by doubling the height of the raster
and thus scanned half a frame, a whole frame, and half a frame and passed the resultant picture through a mixer to
blank top and bottom.
Many happy Sunday afternoons spent with K.M. putting barbed-wire top and bottom of the opening titles of a WW2 picture.
The MKIII digiscans read out of the framestore the part that you wanted!
Anorak off now!
