What is an IMAX cinema: a complete guide to the format with an analysis of technologies

Have you ever walked into a movie theater and seen the sign "IMAX» on the ticket and wondered how this format differs from a regular film screening? Or maybe, on the contrary, you specifically choose sessions with such a mark, but do not fully understand why you are overpaying? IMAX is not just a marketing ploy, but an entire ecosystem of technologies that radically changes the perception of the film. Everything is important here: from a giant screen to a unique sound system, from specially filmed content to the architecture of the hall itself.

In this article we will look at what is IMAX on a technical level - how projectors are designed, what resolution standards are used, and why the picture looks so realistic. You will find out what IMAX different from Dolby Cinema or 4DX, is it worth overpaying for a ticket, and how to choose a film that will truly reveal the potential of the format. We will also answer controversial questions: is it true that in IMAX less advertising, and why some blockbusters are shot specifically for this format. Ready to dive in?

IMAX - is it a format or a technology?

Many people mistakenly believe that IMAX - it's just a big screen. In fact, this is complex system, which includes:

• 🎥 Unique cameras with resolution up to 18K (for comparison: a standard movie is shot in 2K–4K).
• 📽️ Special projectors with a double system of lenses and lamps with power up to 30,000 W.
• 🔊 Sound system with 12+ channels and acoustics designed for a specific room.
• 🏛️ Hall architecture: the screen occupies the entire field of view, and the chairs are located at the optimal angle.

Corporation IMAX Corporation (founded in 1967 in Canada) not only licenses technology, but also certifies cinemas. So that the hall receives the right to be called "IMAX", it must meet strict standards: the minimum screen height is 22 meters, the projector must support the proprietary format 15/70 mm (15 perforations per frame, 70 mm film width), and the sound is reproduced without distortion even at maximum volume.

An important caveat: not all IMAX films are shot on film cameras - many blockbusters (for example, Dune or Avatar) use digital cameras ARRI Alexa IMAX, but even in this case, post-production adapts to format standards.

How the IMAX screen and projector works: technical details

Main difference IMAX from a regular cinema - this screen aspect ratio. The standard film is in the format 1.85:1 or 2.39:1 (widescreen), whereas IMAX uses 1.43:1 or 1.90:1. This means that the picture takes 40% more areathan in a classic hall. For example, screen IMAX in Moscow "Karo 11 October" has the dimensions 26 × 19 meters - it's like a five-story building!

Projectors IMAX there are two types:

Projector type	Resolution	Source	Features
IMAX 15/70 mm	18K (equivalent)	Film	Maximum quality, but requires a physical copy of the film. Used in 100+ halls around the world.
IMAX Digital	2K	Digital DCP	A more affordable option, but the quality is inferior to film. Distributed in 1500+ halls
IMAX with Laser	4K	Digital	Latest technology with laser projectors, contrast 5000:1 and brightness 60,000 lumens.

One more trick IMAX - this is hall geometry. The seats are positioned so that the viewing angle of the screen is at least 70° (in a regular cinema - 30–40°). This creates an immersive effect: the viewer literally “drowns” in the frame. For example, in the flight scene from Interstellar, you will actually feel like you are flying through a wormhole.

IMAX vs Dolby Cinema vs 4DX: which is better?

Viewers are often confused IMAX with other premium formats such as Dolby Cinema or 4DX. Let's look at the key differences:

• 🎬 IMAX: focus on screen size And detail. The sound is powerful, but without surround effects. Suitable for visually rich films (Avatar, Top Gun: Maverick).
• 🔊 Dolby Cinema: emphasis on sound (technology Dolby Atmos with 128 audio tracks) and color (contrast 1 000 000:1). The screen is smaller than IMAX, but the picture is brighter. Ideal for drama or thrillers (Dune, Oppenheimer).
• 💺 4DX: adds physical effects — movement of chairs, wind, splashes of water. The technology does not affect the quality of the picture or sound. Suitable for action films (“Fast and Furious”, “Avengers”).

Which format should I choose? It all depends on the movie:

• 🚀 Space epics (“Interstellar”, “Gravity”) → IMAX (scale of the universe).
• 🎭 Dramas with deep sound (“1917”, “Sound of Metal”) → Dolby Cinema.
• 💥 Action movies with chases (“Mad Max”, “Mission: Impossible”) → 4DX.

How much does an IMAX ticket cost and is it worth paying extra?

Ticket price in IMAX in Russia varies from 800 to 2500 rubles depending on the city, cinema and show time. For comparison: a standard ticket to the same film will cost 400–1200 rubles. The difference is 2–3 times - is it justified?

Let's calculate the “dive cost”:

• 🎟️ IMAX ticket: 1500 rub.
• 🍿 Popcorn + cola: 600 rub.
• 👓 3D glasses (if the film is in 3D): 100 rub. (sometimes included in the ticket).
• 🚗 Parking/travel: 200 rub.
• = Total: 2400 rub. per person.

Is it worth it? Yes, if:

• ✅ The film was made specifically for IMAX (for example, Oppenheimer, Dune, Top Gun: Maverick).
• ✅ You are watching a blockbuster with large-scale scenes (space, battles, racing).
• ✅ Detail is important to you (for example, in Avatar you will see every Pandora scale).

No if:

• ❌ The film is a comedy or melodrama (the effect of IMAX minimal).
• ❌ Used in the hall IMAX Digital (not film or laser).
• ❌ You are sitting in the front rows - your neck will hurt from throwing your head back.

How to save on IMAX tickets?

1. Buy tickets for morning shows (up to 30% discount).

2. Look for “birthday” or “student day” promotions.

3. Some cinemas (for example, “Karo”) give a discount when purchasing online 3+ days before the show.

4. Subscribe to cinema newsletters - they often send promotional codes.

How to choose the best seat in an IMAX theater?

B IMAX The placement of the chair is critical: the wrong choice can ruin the entire experience. Optimal zone - central rows, at a distance of 2/3 from the screen. For example, if there are 10 rows in the hall, take row 6-7 in the center.

What to avoid:

• 🚫 First 2–3 rows: Your neck will hurt when you tilt your head back, and the sound may seem too loud.
• 🚫 Extreme places: Perspective distortion (fish-eye effect).
• 🚫 Last rows: The immersion effect is lost because the screen does not occupy the entire field of view.

In some cinemas (for example, IMAX in "October") yes VIP boxes with comfortable seats and increased legroom. Their cost is 30–50% higher, but the comfort is worth it, especially for films longer 3+ hours.

Check if the film was shot with IMAX cameras (there is a list on official website)

Choose a seat in the central rows (optimally - 60–70% of the length of the hall)

If the film is in 3D, bring your glasses with you (they are often better in IMAX than in regular theaters)

Arrive 20 minutes in advance - IMAX takes longer to check tickets due to limited number of seats-->

Frequently asked questions about IMAX (FAQ)

🔍 Does IMAX have more advertising than a regular movie theater?

No, it's a myth. The amount of advertising depends on the cinema's policy, not on the format. In some networks (for example, Karo) before sessions IMAX show less advertising, since the ticket is more expensive. On average: 15–20 minutes Rollers vs. 25–30 minutes in standard rooms.

🎧 Can I use my own headphones in IMAX?

Technically yes, but not recommended. Sound system IMAX It is designed for the acoustics of the hall, and headphones will distort the sound. If silence is important to you (for example, for a child), it is better to choose a session Dolby Cinema — the sound is more balanced there.

Yes! B IMAX are used polarized glasses with larger lenses (to cover a wide field of view). They are lighter and do not darken the picture as much as cheap glasses in standard rooms. Some cinemas (eg. IMAX in "October") give out points RealD 3Dwhich you can take with you.

🍿 Is it possible to eat popcorn in IMAX?

You can, but keep two things in mind:

1. Sound in IMAX very loud (up to 105 dB), so you may not hear dialogue if you're actively chewing.
2. Some rooms (for example, with boxes) have stands for food, but in standard rows it is inconvenient to hold a glass and popcorn - there is not enough space.

Tip: Take popcorn in a small package and avoid sticky drinks (risk of spilling on a chair or neighbor).

📱 Is it possible to shoot the screen in IMAX on a phone?

Technically possible, but:

• 🚫 This violates cinema rules (they may kick you out).
• 📵 The quality will be terrible: IMAX uses protection against piracy (for example, infrared tags that spoil the video when shooting).
• 🔦 In some halls there are surveillance cameras that record filming attempts.

If you want to preserve memories, take a photo of the hall before the start of the session (when the logo is lit IMAX).
