P3D RE: PHOTO-3D digest 2391

Friends,
Reference WIDESCREEN MOVIES.

This is where The Widescreen Centre is on home ground.       The Bolex WIDESCREEN lens,  or anamorphot,  as it was called should not be confused with their 3-D attachment.

The widescreen lens was made by the German company of MOELLER and had a compression factor of 1.5:1 giving a screen format (from 8mm or 16mm) of 2:1 only.

The history of 'CinemaScope' is a little more conveluted and began in 1953 just after the introduction of CINERAMA.   Because it is a 2x compression and was originally used on the old Academy format the actual Aspect ratio would have been 2.66:1  but 20th Century Fox degreed that the films should have a 4-track magnectic stereophonic sound track,  this reduced the aspect ratio to 2.55:1,  then someone had the idea of 'recovering' the lost height of the original Academy format (whose aspect ratio had been reduced in height when sound hit the movies), and   -  after a number of other alterations,  including the British Rank Organisation insisting that they should also have optical sound, the aspect ratio ended up as today's 2.35:1

We have been selling lenses for the production of both widescreen and CinemaScope format amateur films for over 28 years.   We still sell these lenses both for 35mm slide shows (aspect ratio 2.25:1 using a 1.5x compression) of, nowadays the 16/9 format of widescreen t.v.

Any questions?
