The Tech Behind IMAX

Overview of IMAX Technology

  • IMAX involves advanced technology for creating immersive presentations.
  • Production costs can reach $2,000 per minute.
  • IMAX aims to enhance the viewing experience, enhancing the suspension of disbelief for audiences.

IMAX Laser Projector

  • Critical components are assembled for the IMAX laser projector.
  • Transition from original projectors (15,000 watt Xenon bulbs) to digital required significant changes.
  • Digital projectors use prisms, which result in lower contrast and image quality compared to IMAX's new designs.
  • IMAX's new projector uses no prisms and employs three color lasers for improved image quality.

Precision Alignment

  • Alignment is crucial for accurate color representation in the projectors.
  • Requires placement precision down to microns.

IMAX Film Cameras

  • IMAX cameras have been used in extreme locations (e.g., International Space Station, Titanic).
  • IMAX uses 65mm film with 15 perforations, offering more than 10 times the area of standard 35mm film.
  • 65mm film provides an approximate resolution of 18K, richer in texture and color compared to 4K digital cameras.

Limitations of Film

  • IMAX film cameras are heavy (around 55 lbs) and produce loud sounds due to motors, making them less suited for Hollywood filmmaking.
  • Film length of 1,000 feet lasts only about 3 minutes, limiting shooting time.
  • IMAX has only nine analog film cameras, all dating back to the late 1990s.

New Film Camera Development

  • IMAX is developing a new film camera to compete with modern digital cameras.
  • Features include:
    • Made from composite materials (carbon fiber, titanium)
    • New optics
    • 5-inch full color display
    • Wireless connectivity
    • Uses 15 perf IMAX analog film in 18K resolution.

Remastering Process

  • IMAX collaborates with filmmakers to enhance visuals and sounds in their theaters, ensuring films look good on larger screens.

IMAX Theater Design

  • Stadium seating is steep to give every seat a clear view.
  • Up to 12 speakers are used to ensure uniform sound volume.
  • Screens have a taller aspect ratio and curved design for optimal viewing.
  • Screens are made from perforated vinyl with a proprietary silver coating for uniform brightness.

Theater Operations

  • IMAX theaters are monitored and calibrated daily for optimal performance.
  • Operations are connected via the internet, allowing technicians to remotely troubleshoot issues.
  • 95% of issues can be resolved remotely.

Importance of Immersive Experience

  • The immersive quality of IMAX films enables viewers to feel part of the content, enhancing the suspension of disbelief.
