Reald 3d what is it

RealD cinemas also use the passive circular polarizing technique to achieve 3D which allows viewers a clear image even when turning or tilting their heads.

Imax Digital 3D: This is a similar format that also uses polarizing glasses. Imax Digital 3D is an evolutionary improvement of analog Imax 3D theaters that have been around since Its long history is evident even in the much newer Imax Digital 3D theaters since they still utilize the linear polarizing technology of its analog predecessors.

Unlike RealD, Imax 3D movies are less tolerant of head movements. Viewers have to avoid tilting their heads, though some turning—probably unavoidable due to the massive Imax screen format—is possible. Note: We will not be discussing analog Imax 3D theaters for this article since it is meant to contrast the two dominant digital 3D formats currently available in cinemas. Theater audiences are paying more for Imax 3D movies for a few possible reasons.

Sometimes, it may occur to many people how watching movies in the theatre feels so extraordinary than watching it on a regular TV screen. Find out here! The movie theatre companies are more reliant on latest and existing technologies to offer seamless watching experience for their audience.

In the old times, formats used to be very basic, even in the early 21th century, there were not many innovations seen in movie-theatre arena. But then 3D otherwise called RealD 3D came into existence in this arena which succeeded wonderfully.

This technology use the projectors with polarized light that creates an delusion of depth in the images, making movie-watching highly immersive. IMAX theaters have the biggest screens than any other theatre formats.

This is the version that is higher than the standard 35mm film screens we see in the theaters. Real D 3D and IMAX are both latest genres of cinema technology that give cinematographers more choices for editing and projecting the movies in a more riveting way.

Imax 3D is the movie format that many theatres have these days. Bigger is much better when it comes to enduring the latest blockbuster films and IMAX guarantees to do so.

That way your eyes and brain can't detect sickening flickering. And because the resulting light waves move in spirals, they can hit your glasses at different angles and still make fantastic images. That means you have more leverage to tilt and cock your head while you watch. The system isn't perfect. At certain angles, viewers may still see ghosting , which is a type of image leakage. In ghosting, one eye may see the tiniest glimpse of images meant for the other eye. When this happens, it can disrupt the fun and may make you feel a little woozy.

Another challenge for RealD with ZScreen is brightness. As the projected light moves through all of those filters, there's tremendous light loss, meaning the movie you see looks darker than it should.

To counteract this phenomenon, some theaters use silver screens. Silver screens have actual silver dust embedded in them. The silver is so reflective that it reduces light loss and maintains more brightness than a modern white, matte screen.

Silver screens are actually a throwback to the olden days of movie theaters. Early projection systems had the same handicap as era RealD systems — they were just too dim and required very reflective screens to maintain sufficient brightness for audiences. Silver screens might be a primitive technology, but they are more expensive than basic white screens, and as such, they're another drawback for owners looking to invest in 3-D.

The initial RealD 3-D system that's equipped with first-generation ZScreen technology is also the most widespread 3-D projection system in the world, available in many thousands of theaters.

This version does have some significant limitations, particularly in terms of the size of the screen on which it can project, specifically screens that measure 45 feet 13 meters or less. True to its moniker, it works on extra-large screens up to 80 feet 24 meters wide. The XL is designed to provide more than enough brightness for large screens, making for a bigger and ideally more immersive 3-D experience.

Whether your theater uses the first RealD system or the XL, both work specifically with the company's 3-D glasses. The glasses that you wear during a RealD feature film aren't your everyday polarized eyewear. If you tried to slip on your normal sunglasses during one of these flicks you'd miss out on the special effects and likely upchuck your popcorn , too.

The glasses also have some subtle refinements, such as low-glare frames to reduce scattered light that would distract you from the movie. Each time you buy a ticket to a RealD movie, you receive a brand-spanking-new pair of 3-D glasses. The idea behind this is to provide the best possible clarity for your movie experience, but also to reduce the heebie jeebies you might feel about wearing glasses that other people have already used. After each show, most theaters collect the glasses for recycling.

Some people do keep their glasses for reuse, and others like them just as souvenirs. Some industry insiders feel like those glasses should just gather dust for a while as the 3-D film industry recalibrates itself.

Ticket sales for 3-D movies are sliding downward, and many pundits blame poor sales on overuse of the effect, in addition to poorly produced conversions of 2-D to 3-D, which often results in ugly, almost unwatchable films. Movies that make full use of the potential of 3-D, such as 's "Avatar," were first imagined as multidimensional experiences.

Whether 3-D will be around for many years is up for debate. What's certain is that companies like RealD will continue to innovate and refine the technology behind 3-D in the hopes that it will capture audience imaginations like no other cinema experience in history. I rarely go to theaters to see movies, but I was one of the millions and millions of people who made time to watch "Avatar" on the big screen. It was worth it. It was a sensory experience that made me wonder if it would change the way movies were made.

Half a decade later, it seems as though the 3-D trend has overstayed its welcome. Too many 3-D movies are 3-D just for the gimmick instead of the story, and as we all know, it's the story that matters and not the technology. Perhaps more directors will put 3-D to intelligent use soon, or maybe 3-D will fade into obscurity for a few more years before the next generation of projection technology promises a permanent 3-D revolution Sign up for our Newsletter!
