Last night we went to the Corso cinema to watch Toy Story in 3d. We took with us 3d glasses our daughters had bought at Sihlcity. Nothing was said about glasses when we bought our tickets.
As we were sitting waiting for the film to begin, one of their staff came up to us and gave us a pair each. We told him we already had glasses, but he explained that the system in Sihlcity is different so we needed new ones
5 minutes later he appeared again, this time asking for 3CHF for each pair of glasses,which we paid.
During the film my wife tried the glasses from Sihlcity and they worked perfectly well
Can anyone confirm if different cinemas use different 3d systems? I must say I am sceptical...
Basically I feel cheated - if we needed specific glasses they should have told us when we bought the tickets. It's the principle not the money...
I don't know about in the cinema, but as I understand the glasses needed for new 3D TVs will be proprietary for each manufacturer, which is to say glasses for one maker won't work with the TV of another. That said, it still stinks that they made you pay.
I noticed while watching Avatar that the glasses supplied by the theater (PatheĢ) had some sort of electronic eye on them and the polarization changed ( ) depending whether you were facing the screen or blocking the eye in some way.
If the eye was blocked when facing the screen, the 3D effect was cancelled out...
I imagine this way people are less prone to headaches and nausea that are often complaints with regard to 3D movie viewing so maybe they wanted you to use their glasses for your own comfort?
That is not the case with the ones from Corso... they are simple polarising lenses. As far as I can tell they are identical to the ones we have from Sihlcity, apart from the shape of the lenses.
I saw the same movie, but had been informed that for Toy Story 3, you needed the Real 3D glasses. I have also bought glasses necessary for the Sihlcity presentations.
I am not sure if the difference starts with the filming of the movie or it's projection or both that creates the requirement for specific glasses. Reasonably certain that there's not "one" standard yet
Basically to get a 3D effect you need to have different images delivered to each eye. The main two systems I know of being used in the movie Theater are polarizing, where the light is polarized clockwise or anti clockwise for each eye, and interferance use but the Dolby system, which uses slightly different wave lengths of the light reaching each eye.
Depending upon the system in use you will need different glasses.
We did - they said that as we'd opened the packaging of the ones they gave us (before they came back asking for money...) they couldn't provide a refund.
I've mailed them and am waiting an answer. I expect I'll be waiting for a long time!
