We're proud to be one of just a handful of theatres in the world offering dual projection systems: our IMAX 70mmfFilm projector sits alongside our 4K Laser digital system in the projection booth.
What does IMAX 70mm (or IMAX 1570) mean?
1570 refers to the dimensions of the film frame, which is 15 perforations (the small holes that run along the edge of each frame and allow the film to be pulled through the projector) in length by 70mm in height.
This is not to be confused with standard 70mm film, which has just 5 perforations per frame - less than a third the size of a 1570 film frame. Explore the IMAX 70mm difference.
What’s the difference on screen?
A bigger film frame allows for a few significant differences in presentation, most notably a much larger projected image and far superior image quality. It’s often reported that IMAX 70mm film has native resolution of up to 16K, far greater than any other film or digital format.
The other key difference is the aspect ratio of the IMAX 70mm presentation. Aspect ratio refers to the relationship of the image width to its height.
Full-frame IMAX 70mm has an aspect ratio of 1.43:1, which means the image width is 1.43 metres for every 1 metre of height. This is considerably greater than mainstream cinema presentations, which usually display a 2.39:1 aspect ratio.
Ultimately this means a full-frame IMAX 70mm scene will fill the entire 23-metre height of our screen, significantly more than the 13 metres used by a standard 2.39:1 presentation.
What’s so special about it?
IMAX 70mm film has remained the largest and highest resolution film format available for over 50 years. World renowned cinematographers and directors like Christopher Nolan have mastered its capacity to provide the ultimate expression of their craft.
The combination of an incredibly high resolution format, the natural, warm and earthy tones of native film print and the sheer scale of how it looks when presented on the world’s largest screens translates into a truly immersive and unparalleled way to experience a movie, which cannot be replicated elsewhere.
When was the IMAX 70mm system installed?
Our IMAX 70mm film projector was installed in 1998 when the theatre first opened to the public. In 2015 it was removed from the booth to make way for the IMAX 4K dual Laser projection system, the first Laser projector ever installed in Australia and only the fifth IMAX Laser system in the world at that time.
Ownership of our IMAX 70mm system was retained, and it remained in storage. Just two years later, negotiations with IMAX Corporation resulted in the reinstallation of the IMAX 70mm system in time for the release of Christopher Nolan’s WWII epic DUNKIRK in July 2017.
