Here is a Facebook video showing the installation of a second NEC projector needed to get brighter images while showing Avatar on the giant curved screen.

Did I really see the tech remove and replace the xenon lamp without protective clothing and with others in his presence? [Eek!]

That's not exactly setting a good example, especially in such a public venue as FB.

Yeah, no kidding. That's a big ass bulb as well. Big boom if that baby goes off.

....a truism spoken often by our own late, great John Pytlak.

So has anyone seen Avatar at the Dome? I'm going to be in L.A. for a few weeks after 1/3/10 and was saving this picture to see there, but I've been a little concerned about how it's going to look, given the Dome's notorious projection issues. The back-up plan is the lie-MAX at the Century City 15. Any reports?

Lets see... I lost track of how many techs there were in that video but if I'm right there was a lamp change guy(without any protection at all), a lens removal guy... a lens handling guy... at least two guys to carry it up the stairs... The narrator that liked video more then he liked 35mm film... And to top it off they moved a $80,000.00 projector on a $45.00 plastic cart... Hilarious! That whole job should have only taken two or three guys at best.

Just a classic LTI/Philips, LTIX-6000W-HEHS "Helios". "Dang!" I've had two of them fool bulbs (3000w-HEHS) experience seal loss well under warranty hours.

I've never seen a tech wear protective stuff when doing bulb changes... even though, when a "Helios" blows, with being filled more with the gas and the quartz is thicker than normal, they DO get pretty nasty when you destroy them... and that fool clamshell carrier for the LTi's that gets wrapped with the velcro strap is a total joke when it comes to safety. Both the cheap plastic covers will actually shatter along with the straps rips apart quite easily when a bulb explodes inside.

At 900hr for warranty, that complex is gonna have a good sized bulb bill from STRONG per year being that bulb has to be pulled prior to warranty hours.

Hate to see the price for that reflector - prob close to $7k being all glass - why you pull bulbs before warranty.

Unit looks like a new NEC-2000, which is DCI-2 complient.

Can't get over the design factor of the NEC: On the right side under the control panel, is the sockets for the BNC Video inputs along with other inputs, and you think that the design team of NEC would, at least, have all of that under a cover of sorts instead of just hanging on the outside of the cabinet.

Ya, looks like "too many hands in the cookie jar" - bumping into each other like that ..

It's just an example of too many headless chickens. I could do all that with just one assistant and I bet most of the guys here would instead of having all those lore guys each specific for a task. Most probably those guys have an ISO and are bound to follow procedures! so no one else is allowed to touch another mans' job [Smile]

What was so special about that prototype base I could not understand! [Eek!]

This was a type of video which states 'Look at us we suck'

The narrator seemed lost more like a sales type who didn't know what he was talking about. As for them ripping the whole thing down it seemed pointless. That cart was a piece of crap mainly because they didn't want to invest in actually setting up a second base or moving the base because they will just be moving that projector back down to where it came from when they find a new movie. Did anyone see the super highlight 2 in the background.

Yeah, because its quieter in the booth.

And that was his only remark about why digital is better than film.. NOT

Posted by Mark Gulbrandsen (Member # 72) on 12-22-2009, 08:26 AM:

Another fine point is that side by side is not the best route to go for dual projector. Stacking gets the lenses closer together by a long shot. A proper stacking rack is not all that expensive to make either... about 2 grand. The Super Highlite in the background was one of the three cinerama projectors, the rest of the equipment ther is all Kinoton far as I know.

And what was that remark about the Anamorphic being used when you have a long distance!!??? [sleep]

Posted by Steve Guttag (Member # 268) on 12-22-2009, 05:55 PM:

Mark, no...use a Christie and a Barco projector with the Barco on the Right side...this will get the lenses the closest!

But yeah...use an anamorphic lens for those long throws! That makes sense [Roll Eyes]

Posted by Mark Gulbrandsen (Member # 72) on 12-22-2009, 06:33 PM:

Yea, no reason why not to... You're right about that getting the lenses very close. I still prefer stacking method because of the smaller footprint and I feel it gets the lenses close enough together to eliminate most paralax associated artifacts... especially with a long throw like they have there.

I'd still like to see a dualin one D-Cinema projector built like the Imax GT twin rotor job with the lenses literally right above and below each other. Of course that'll never happen because companies like Christie are attempting to program us to think that single projector Real-D is better [puke]

"One thing I like about digital projectors is that it has the ability to crop".

Ah ah ah. I'm telling the DCI police.. [Big Grin]

What a bunch of morons in that video. [fu]

Posted by Kevin Fairchild (Member # 4985) on 01-03-2010, 02:31 AM:

So how exactly does a dual projector Xpand 3D setup work? Do both projectors display the same image? This wouldn't be like a double Dolby/Masterimage where each projector has a different eye.

So in double Xpand systems, projectors 1 & 2 show ABABAB in triple flash.

In double passive glasses, projector 1 shows image A, projector 2 shows image B.

Right??
