Let’s quickly recap then what is special about IMAX film. Most movies today are shot using digital cameras, or if on film, it’s 35mm. IMAX 15/70 film frames are considerably larger. The number 15 refers to each frame having 15 perforations across – these being the holes that are used to hold the film as it moves through the projector. The 70 refers to the fact that the frame is 70mm tall. This compares with regular 70mm or 35mm film stock, which has only five perforations down. (IMAX film moves through the projector horizontally, hence the perforations are at the top, whereas other formats move vertically). IMAX 15/70 frame is, therefore, 8.3x larger than 35mm and 3.4 times larger than 70mm – and the result is unprecedented quality.
Hier wird die Auflösung gefeiert und von "immersion" geredet, während es bei 8k-Projektion kurioserweise immer hieß, das brauche man nicht. :)This large frame allows much more fine detail to be captured, delivering richer colors and greater contrast. The highest-resolution digital cinema cameras have 8K sensors, and digital projection maxes out at 4K resolution but some estimate IMAX film stock to have an equivalent resolution of 16K. Let’s leave it to Chris Nolan himself to sum up with his belief that IMAX 15/70 is, “the highest quality imaging format ever devised – [it] gives you an incredible sense of immersion in the image. The clarity, the crispness – it is the gold standard.”
