When I started as a projectionist in 1952 the word "Aspect Ratio" was not in our vocabulary. But later even when widescreen came in, it only needed a new aperture plate and a masked down screen.

With scope came variable screen masking, a complete change of aperture plates, removing the standard lens, and fitting a longer focus backing lens, and lastly swinging down (or up) the mighty anamorphic. There was a lot to remember!

Later came two (or three) apertures on a single plate which pushed over like an old fashioned lantern slide, a turret for the two (or three) main lenses, but still the anamorphic was on its swing bracket.

Even later we had a turret holding two (or three) lenses, the scope lens being permanently screwed onto its backing lens.

Then came long play. This necessitated a long length of black film whilst we quickly carried out the change to scope.

Now goodbye film, all digital and pre-programmed on computer.

Oh yes, I nearly forgot. No projectionist.
