How does an IMAX cinema theater work?

Answer 1

Having worked in the cine industry as an engineer, this is my understanding of how cine camera works.

In general the technology adopted in still camera and motion picture camera are very similar. Unlike a still camera where the film is discretely moved (manually or auto advanced) between each click (to shoot a picture), in a motion camera, the film moves at 24 frames per second while capturing the picture (the shutter being open continuously) unless manually shut by the camera man.

Thus what is being picturized will be exposed in the film frame by frame. (This is very similar to tape recording process).

That reel (of exposed) film with picturization is washed and developed for the film negative. From the negative, film positive will be made (similar to photo printing - photos are positives on paper base while it will be on the film base).

This picture positive film is played back on the theater projector (film moving at 24 frames per second) - to give an illusion of continuous action!

Hope this gives an idea (I may not have given a complete detail of the process - it is just a high level overview!

Thanks

Answer 2

I believe that it is a large projector and the 'screen' is a giant blank white screen.

Answer 3

IMAX movie theatres are very impressive, compared to regular movie theatres. This mainly comes from the size. The screen, sound system and stands are much bigger.
