Back off subject - but I heard from the Arclight Cinema projection manager. There was a singular alignment issue for the showing I saw. They have a leading edge system with unique challenges. And then there is the overly curved screen.

But, for those who care, XpanD (shutter glasses) is a very good system - maybe the best many say. I can't wait to confirm that with another viewing.

Losing what interest I had

Post by Roger Halstead »

I'm an early adopter, and have been since I was a kid and that was a very long time ago.
However, even liking gadgets, I viewed the early 3D movies as a gimmick that required glasses to view. From the viewers even the best of these sound like a gimmick and nothing I'd be interested in, particularly if I have to wear glasses to view the image. From the descriptions I think I'd rather see Avatar on a regular screen. I'd like to see the 3D version as a comparison, but I'm afraid I'd be one of those who wouldn't stay for the ending.

You know....we walk around seeing 3D, all day every day (my apologies to those who have lost one or more eyes, or who have monovision lasik). You can watch your TV as you wish, most of which is trivial, or buy a TV with a really black black, and revel in the apparent additional depth.

No one is asking anyone to walk around with "sun glasses" which will mostly de-3d their real world. No one is going to break anyone's arm ...well outside of a retail outlet of poor ethics.... to buy anything what-so-ever.

But when I see a work of crafted art like Avatar, I (and very many others) might very well put on the glasses (over my present ones) and enjoy a different, beautiful artform.

Roger, to see Avatar is to see a new reference in the use of 3D. My basic thesis of video art is that there are as many ways to enjoy a movie as there are classes of Academy Awards (and more). If the story is engaging, like a book, you do not need any more than a tiny screen in black and white. And I only say that as video relies on the visual and does not generally complete the story in verbage. Before than that, radio shows engaged a generation or two, and always is the written word.

So yes, Avatar in 2D is as loved as in 3D. But there are scenes eg. a snow like falling/floating of particles that come out into the audience that have a unique engaging quality, and as limited as that one scence is, sometimes it is just those short moments that gives what greatness we find in the medium. One of my favorites is Helen Hunt, in As Good as It Gets. One scene where she pours her heart out, garnered an Academy Award.

And in a movie like Avatar, with a lot of big vistas shots, they are net in 2D anyway. In fact in the real world given the nature of our vision, we only really see in 2D all those things that are rather distant. It is a craft to make this technology work, and James with Avatar has brought us the best. And it is NOT the 3D of Red and Blue glasses of old.

Steve, sounds like you are ready to take it home!

Roger, I look forward to seeing Avatar in pristine HD via Blu-ray to my 124" 2.35 screen. I recommend to anybody interested in 3D and the state of 3D art to go have this experience.

Well, I would probably wait until I can go to a projector as this point. That based on assumptions of being able to sync a spinning Dolby 3D 'shifter' wheel, a polarizer wheel, or used with shutter glasses.

On Dolby 3D: It uses the "Wavelength Multiplex Visualization" system. It shifts the 3 primary colors from the projector just a little bit up and down for each eye.

In projection it can be implemented rather easily by the synchronication of the left/right frames with a spinning color shifter wheel. In a theater the white paper example shows a double projector with shift filters for each side. In a single projector alternating frame system, it is a spinning wheel. Thus, I am thinking a Dolby 3D front projector system for the home would be a reasonable assumption for the future.

The coating on the glasses, a set of very narrow filters each allowing only the primaries through - left side slightly tuned different from right side - could be put on perscription lenses, as well as the typical theater glasses. The only 'calibration' issue would be that the projectors 3 source colors match the filters on the lenses.

An advantage Dolby 3D would have in the projector situation is that the glasses' lenses are tuned to the 3 basic colors (with the shifts). Ambient light not in the spectrum will be filtered giving a better contrast.

This all is similar to the polarizing systems, but has the advantage on the ability to use normal glasses (depending on cost to get them coated). The downside is some people might notice one eye notices more red, the other more green. Normally a wash, but in some cases, like DLP rainbow, it may be noticeable. TBD!
