Replacing the World's Largest IMAX Screen
lukehopewell1 writes "IMAX Sydney has replaced its screen — the largest in the world — at a cost of $250,000. Weighing over 800 kilograms, painting the screen took over 12 days and 350 kilograms of paint. Lifting the massive screen and installing it took a year of planning and 31 riggers. A neat photo gallery is included so you can get an idea of just how big a job this was."

Nice, but the IMAX crown goes to La Geode in Paris.
Although it has a slightly smaller screen (1000 m^2), the screen is not planar but hemispherical with a diameter of 36m.
The public is literally at the center of the action, and no cinema and certainly no home theater how ever high end it is can compete with this kind of cinema experience.
Why in the world would it take an entire year to plan hoisting a 800kg screen? That weighs less than my car. A few winches could get it in place without putting even the most fragile screen at risk. I wonder what they did with the other 9 months of that year?
FWIW, I have hung a full-sized non-IMAX screen in about half an hour with zero issues. Not 800kg, but at least 100.
If the only way you can accept an assertion is by faith, then you are conceding that it can't be taken on its own merits
At 4:30 into the video, the CEO of IMAX Australia mentions that they have been using 70mm for quite some time.

On page 7 of the photo gallery they quote the theater's CEO that they'll be using 1570mm film, which commentors were quick to point really means 15/70 sprockets per frame/width. The idea of film as wide as a compact car is interesting to envision, though.
Not Really... I just raised one in New England two weeks ago. We had 13 people up top pulling, 10 more below helping to pull, and numerous other people who were assisting below to keep the screen surface raised as much as possible. There easily need to be that many, as the screen is extremely heavy and difficult to pull up as a dead load. Additionally, ours had a silver surface for 3D, which means you can't touch the screen or you will ruin it.
Then there was the joy of bringing a 60' box holding the screen through a mall, raising it 2 stories in a food court all night, and then raising up the screen itself...
Maybe it's the font but I did a double-take when I read it...

Dunno...but if you're British I believe it's about a third of the size of Wales.

Not true, actually. I recall hearing about an experiment that some IMAX engineers did a few years back, where they put black and white squares in a checker pattern up on the screen. They started with a 2x2 grid of squares, then went to 4x4, then 8x8, etc., but they ended up stopping well before they ever hit 4K because the screen had become gray. What that meant was that the film was not able to provide the level of contrast actually necessary to discern the shapes any longer. In other words, the level of detail it provided was below that of a 4K image.
Of course, the problem with 4K is that the details are so small, even at the scale of IMAX, that viewers would need to sit in the first five or so rows to really be able to appreciate any difference at all. And, as was noted in the video, lighting and quality concerns are still major factors with digitial projectors, more so than the issues with resolution.
Analog has some advantages, to be sure, but they mostly are in the fact that it can provide good enough resolution without other compromises. Digital resolutions surpassed IMAX several years ago, but digital projectors still have enough drawbacks that analog continues to have a place in some of these theaters, though time is running out for that.
Your eye is not a camera. Just because you cannot resolve the space between two dots, does not mean your eye cannot resolve detail at much higher resolution, e.g. vernier acuity

I HAVE A BIG BLACK CLOCK and it could be the font too.
