I wonder if anyone might be able to email me a photo or two of the front of an Imax projector running 3D prints. It is for a non profit club magazine to illustrate an article on 3D. It should be one that you have taken and is therefore your own intellectual property.

If the two films and lenses can be seen, it would be of advantage. Perhaps a wide shot of the whole projector and a close up of the transport. Many thanks.

1. Do not post email addresses on the boards outside of the For Sale forum.

2. Imax does not allow the publishing of image of their technology. Anyone sending you photos will likely be in violation of a confidentiality agreement.

In our dealings with this issue (built in disclaimer, there), It was the inside of the projector that IMAX won't allow photos/video of. We talked to them a while back about a local news crew coming in and filming and they said it was all right as long as they didn't go near an open projector, which of course the film crew tried to do right off.

Thank you all for the good advice. It is apprciated.

If you had photos of the left and right eye frames of a 3D film side by side, could you do the "magic eye" technique and see it in 3D?

Uh, no?
Check out this video on Youtube.com that describes how the 3D works in IMAX

Not the "magic eye" technique, but there is a technique called "free viewing" in which you do not converge your eyes on a single point, but relax them so each eye sees the correct frame. That takes plenty of practice, but there's an easier way, IMHO: "Cross-eyed" viewing. Put the left frame on the right, and the right frame on the left. Cross your eyes as you're looking at them. You'll see three images, the middle one will be in 3-D. Takes a little practice, but works for me.

If you are a Film-Tech member, there are some photos of IMAX 3D projectors in the warehouse:

I just looked at the Discovery Channel Europe and they have a program that is called 'How it's made' they showed the whole fabrication process of the 3D projector. From aligning the lenses (many tiny lenses becoming one giant one) to how the roling loop process works. This all in just 7 minutes or so... Maybe you can look it up somewere.

EDIT: OW I am stupid! There is another post in this forum that links to the show... [sleep]

(it's not working though)

Posted by Mark Lensenmayer (Member # 134) on 03-26-2007, 07:53 PM:

There is no link to the show itself, just the website of the program. The HOW ITS MADE website does not show excerpts of programs.

The Imax segment might be available out on the web somewhere, but I am not aware of any locations at this time.

That's interesting. I was installing a sound system in The Glasgow Science Centre a couple of years ago and took a tour of their IMAX booth. The Technical director who took me up to the booth wouldn't let the operators open the projector, and I had to leave before they threaded for the next show. He said I was the competition and IMAX's patent was almost expired.

You think thats bad former Film-Techer Steve Kraus was once grabbed by security guards at Cesars Palace for taking a shot of the Omnimax Booth there... this was in its last days.... I am pretty sure they confiscated the film from hiz camera. It was totally rediclous!

I have detailed close up photos of the SR projectors and for quite a whilea had free access to a closed Imax theater that had a pair of them.

I did a couple of IMAX replacements a few years ago. We gave them an offer for the screens and speakers, but their techs came in and cut the screens down and threw them in the dumpsters out back when they picked up their projector.

Then how do you explain all the images of the Imax gear on the pictures page? Also, none of the many Imax booths I've been in have signs specifically forbidding pictures being taken.

Richard,

That Lied Imax booth must have almost killed off that whole museum! I bet they were silently cheering as the machine was leaving the booth.

Another factor that makes IMAX' attitude over photos more than a bit odd is the arrangement of the booth at several IMAX theaters I've visited: behind floor to ceiling glass windows and visible to the public fixing to watch the movie! You can see booth personnel threading the movie and then watch the projector lift into position. What's going to stop people from taking photos of that -especially with how digital camera technology has proliferated?

I think IMAX needs to get over themselves. Competitors like Iwerks already know every last detail about the inner workings of a IMAX 3D projector. The general public isn't going to do anything with that knowledge, provided they even care at all in the first place. After all, "digital" has all the glamour these days, not that icky analog film.

Posted by Richard Hamilton (Member # 321) on 03-28-2007, 11:50 AM:

Mark, I assume your talking about the Lied museum in Hastings, not Vegas. They are thriving, and yes, this was one of the replacements I did.

Posted by Mark Gulbrandsen (Member # 72) on 03-28-2007, 12:05 PM:

Yes, the one in Hastings, I saw Everest there when it opened. Thats not exactly in the center of an urban area... in a smallish town instead. The Imax had to be very draining of finances or they'd have kept it.

When I said "technology", I was referring to the actual machinery, ie the stuff under the hood, not the containers it's in. I know you're smarter than that.

Posted by Mark Lensenmayer (Member # 134) on 03-28-2007, 12:30 PM:

Well, they must not be too worried about the MPX machine, because that HOW ITS MADE feature shows pretty much all of the transport mechanism, including the rotor. It clearly shows film moving through the transport, including a small explanation of the rolling loop.
