IMAX 3D Projector

Shows the inside of the IMAX Projector and how it works. This model looks much more compact than other models. It is probably a new design.

Note that most IMAX theaters popping up in recent years use IMAX digital projector. No film is involved, hence the film handling part of this video does not apply in those situations. Digital IMAX movies are transported by multi-giga byte computer hard disk.

IMAX 3D uses linear polarization. Tilt your head and the 3D effect is screwed up. Newer Real-D 3D solved that problem. Compare them by watching http://www.time.com/time/video/player/0%2C32068%2C75184978001_1976624%2C00.html

Hve they made 3D projectors that doesn't require glassess yet?

[cplai]

@navylaks2 Probably not at movies for a while due to the difficulty of scaling up the technology for such big screen. Perhaps futuristic holograms like in Star Wars movies. For 3D TV without glasses, Google the word "HR3D" to learn more about a new technology by MIT Media Lab. Notice the date, it is this week's news.

@navylaks2 Samsung, one of the biggest players in big screen TV, said like 2 months ago that 3D TV without glasses is still 10 years away from production. I am not sure if they knew about MIT's HR3D back then. I hope they will change their prediction after the recent news from MIT.

Why You Probably Shoudn't Waste Your Money for IMAX Digital

Example: Lincoln Square Imax Screen Size 76x97 feet (23x30 meters)

15/70 Imax Film = 18K Digital Quality

Imax Digital: Empire 25 Imax 28x58 feet (8.5x18 meters)

2X 2K Projection Or Dumming Down Imax Experiance

ITS NO LONGER THINK BIG BUT THINK SMALL

@FidelCastro128 I totally agree with you. If you read all my comments made so far, I have repeated and repeated to emphasized that this video only applies to the original IMAX theaters. IMAX no longer maintains their own standard regarding the size of the projection screen. Today, IMAX only means the equipments are made by IMAX and there is no guarantee you would get a big screen.

I thought IMAX was being able to view above you and and down toward your feet like at the Science Theater in San Diego. Spent the extra money to see Toy Story 3 in IMAX and was sorely disappointed...not at the movie but the IMAX screen..

@cojute06 Today's IMAX is no longer what it used to be. In San Francisco Bay Area, there are only two IMAX screen that are huge. All other so called IMAX screens are just regular size screens.

IMAX is going all digital in there new theaters, unfortunatly.

[osclarkos]

some really good stuff here

[smuggecko]

brilliant video

[nurtester1]

@FidelCastro128 In my opinion film is still better than digital. I do not mean only movies, but also pictures. If you have a (very) good 35mm Photographic film (or even more like 70mm) you can easily beat the quality of digital (film) cameras. Beside it is more exciting to see a "real film" in cinema instead of any digital stuff which is called today a "film"

[VerseChorusCurse]

I guess that's what you'd call aperture science no?

[kylespopups]

@navylaks2 it is nearly impossible it takes a grooved surface for no glasses 3D to work and with projectors only showing on a flat surface you have no way for your eyes to distinguish left from right angles with that said they could just put a giant tv on the wall of a movie theater.

[xJOxJOHNxDOEx]

Ich nehme einen wieviel macht das ? ;-)

[Dreamwavestudio]

looks expensive, two beamers and some polarisation foil will do the thing, for under $1000,-

[sayrith]

The film goes through a beating. 

[navylaks2]

@cplai

I know tv-screens have it, and it'll mean that in the future less and less people will go the cinema to watch 3D films because they have to wear the stupid glasses.

It's the glasses that's the big anoying problem for everyone.

If cinemas wants to keap comepeating with tv and illeagal downloading they need to find a method without them.
