In the rigorously managed humidity of the projection room at the Science Museum, Matthew stretches out two items of movie over a lightweight field.
The room cannot be too dry or the movie would possibly curl or flake.
He desires to indicate me the scale of the IMAX 70mm, in comparison with the 35mm movie usually used “back in the day” in most multiplex cinemas.
“There’s no audio on the IMAX frame,” he says, “they use the full image area for just the picture. The sound is separate on a hard drive.”
By the time it’s beamed onto an IMAX 1.43:1 display – a uncommon, practically sq. facet ratio – audiences get a full body immersion.
Matthew holds an outdated strip of IMAX 70mm as much as his shoulder, the different finish touching the ground.
“This is approximately one second of film – just under six feet (1.8m) long,” he says.
