Explore the difference between Ahmedabad’s Gujarat Science City IMAX and modern digital IMAX theatres in India. Know why the 15/70mm film IMAX is considered the last true Giant of the film world.
New Delhi: When people talk or search about IMAX in India, they usually imagine a massive screen, booming sound and a premium movie experienced inside a modern multiplex screens in cities like Mumbai, Delhi, Bengaluru or Hyderabad. But what most viewers don’t realize is that all IMAX theatres are not same.
However, very few know that India has a rare and authentic only 15/70mm IMAX film theatre located at Gujarat Science City in Ahmedabad.Unlike the digital IMAX screens, this theatre represents the original large-format of IMAX experience.
It is a contrast between analog film heritage and modern digital cinema technology, and this cinematic immersion, making Ahmedabad’s IMAX one of the most unique in India.
What is IMAX?
IMAX stands for ‘Image Maximum’ and is a high-performance cinema format designed to provide a far more immersive viewing experience than standard movie theaters. It achieves this through specially engineered projection systems, ultra-large screens, and advanced sound technology that combine to create a powerful sense of realism and depth.
An IMAX experience is typically known for:
- Extra-large screens that fill a wider field of vision
- High-resolution visuals with enhanced clarity and detail
- Immersive framing that makes audiences feel “inside” the film
- Advanced surround sound systems for impactful audio experience
However, it’s important to understand that not all IMAX theatres are identical. In India, IMAX generally exists in two different formats:
- 15/70mm Film IMAX (Rare, legacy format):
- Uses physical 70mm film reels and represents the original, large-format IMAX experience.
- Digital IMAX (Modern multiplex standard):
- Uses 4K laser or xenon digital projection, optimized for convenience and frequent commercial film releases.
These two formats may share the IMAX name, but they differ significantly in technology, screen scale, and overall cinematic experience.
