Why is imax screen curved




















Instead of developing and evolving their high-quality brand, the new owners of Cinerama diluted its value with a much cheaper technology, but they still called it Cinerama, figuring people wouldn't notice the difference, or would think it was better, because even though the picture lost fidelity, the join lines were gone. You know what? People did notice. By the end of the sixties, Cinerama inc. It wasn't the unwieldiness of the format that killed Cinerama, it was the new owners' financial decision to pass off a cheaper version as the same thing.

And where have we been seeing that kind of thing lately? Imax has so muddled their brand already They had a 70mm alternate format, Omnimax now called ImaxDome - shot with special fish-eye lenses, intended to be shown through the same kind of lens inside a dome screen. But, they have been routinely showing flat-produced Imax movies on curved dome screens, and fisheye Omnimax movies on flat Imax screens, as if there were no difference.

Each looks awful on the other, but they're presented as if they're all the same. Adding to the confusion are these acronyms for more variations Imax has introduced MPX refers to MultiPleX, but according to Imax folks only indicates situations where some reconstruction was done to convert two smaller plex rooms into one big one, and only using 70mm.

So it's supposed to mean original 70mm Imax film shoehorned into an existing multiplex. Got that? Sometimes the original aspect ratio is presented as is, sometimes not. Then came the latest variation, a 2K digital version in converted multiplex rooms.

It's not a situation where any reconstruction of the theatres, or reconfiguration of the seating was done, although some of their PR leads you to believe so. It's simply the biggest, or one of the biggest, screens in an existing multiplex, pushed up closer to the seats. Usually a screen that has a bit wider aspect ratio than the big Imax square screens. Still with me? And when Digital Imax is run on some screens that are "Squarer" and others that are somewhat wider These are all different animals, not just variations of the same breed, but they insist on calling it all Imax.

And with all those variations, there isn't much standardization of the brand, anymore, is there? So how do you really define Imax? Well now, they're hedging and backpedaling like crazy, claiming their "Think BIG" slogan notwithstanding that the true new meaning of Imax is "immersive. You can't sell it as all the same, because it is obviously NOT all the same. They can't hide that, no matter how the Imax brass try to spin or deny it.

The public's on to them, and there's a backlash of ill will for that. There is even a website were you can look up Imax locations and find if it's the original big screen or the little digital version, which has been called LIEmax. While the Imax brand still sort of represents some kind of bump in quality, size, etc, I thought maybe defining the variations in similar, but distinct terms and varying the pricing accordingly could work better than what they are doing now.

There are SO MANY variations, it would take some thinking to clarify them, but by clearly defining what is obviously different, they might possibly have their cake and eat it too, keeping the brand value, while winning back some pissed-off patrons who've been fooled before.

I noticed a local cinema now advertises their full-size Imax screen as "original" Imax. A little standardization wouldn't hurt, but Is it too late already? Imax has typically emphasized height over width.

In original Imax venues, the screen starts well below the first row of seats and rises many feet higher. The top row of seats is typically only halfway to the top of the screen.

Imax has reached a point where it sometimes looks like their screens are taller than they are wide "ahem CityWalk cough". Imax seems to have ignored the fact that that human vision is much wider than it is tall. The laser projector will be available to exhibitors in the fourth quarter of The camera is set to be used first to film select sequences in another Marvel production, 's Captain America: Civil War.

I've skimmed over a ton of info in the Wikipedia article, which is really all you need but this quick and dirty overview should give people the basic concepts. Space and Rocket Center.

The purpose for IMAX to even exist is that it has the capacity to record and display images of far greater size and resolution than a normal camera could. I assume that they were just using the IMAX theater to trick people into thinking that there was something different about it. However, another type of IMAX will shoot films at 48 fps, so the movie may have appeared more smooth.

Most Imax films aren't Omnimax films, so there's no need for Omnimax theaters. Proper Omnimax films are filmed with a special camera with a fish-eye lens.

Projection is done using a similar fish-eye lens, on a domed screen. This makes for a much more immersive experience. Not all Imax films are Omnimax films. In fact, most are not. Regular Imax films can be projected on an Omnimax screen, but will be skewed on the edges, since they weren't filmed in Omnimax. With so few Imax films being Omnimax, there's no great demand for Omnimax theaters, which I can imagine to be more expensive than regular Imax theaters. The Omnimax concept was created for the San Diego Science Centre who wished to supplement their dome shaped planetarium and did not wish to incur the cost of building a stand alone IMAX theatre.

This concept caught on with a number of science centres and it became a point of discussion whether to install an IMAX or Omimax theatre. Sign up to join this community.

A typical IMAX screen is 16 meters high by 22 meters wide approximately 52 by 72 feet , but they can be much larger.

The largest IMAX screen is 30 meters 98 feet high. Imagine standing next to an eight-story apartment building that is wider than it is tall. That's how big the screen is! It is many times larger than the screen at a normal movie theater. Domes can be up to 30 meters in diameter.
