Thanks for the replies! Yeah I saw it in 70mm on a proper flat IMAX screen in Indianapolis opening weekend, and it was WELL worth it and was incredibly immersive (especially the Falcon escape sequence).
I made a special trip just for that and am glad I did. But this time I’m just gonna be in Saint Louis for work and saw that they’re still showing the 70mm print when I’ll be there so I thought I might try to take advantage of it. But seeing it’s a dome theater gave me pause.
I just don’t understand why they show normally formatted movies and documentaries on the domes. It really hurts the experience IMO. And as one person above implied when he mentioned on the dome the falcon escape scene expanded some, but not a lot - you’re not seeing the full image. Since the screen is more or less a circle, it cuts off all the corners. I’ve never seen anything that discusses or calculates this, but I’d bet you’re easily losing 25% of the image. Maybe more.
And it’s all the more baffling when you find out that at least some of the dome theaters can rotate the dome up out of the way and reveal a full size normal flat IMAX screen behind it. The obvious intent being that the theater can show any IMAX film on the proper screen for which it is formatted. But the handful of theaters I’ve been to that have this capability never seem to use it and just project everything on the dome.
It’s a shame too b/c if you ever have the chance to see a film that was actually shot for the dome with the special lenses and everything they really are quite amazing. And unlike a normal film on the dome, you don’t have to lie flat in your seat and stare straight up because the special fisheye lense they use is calibrated to put the focus near the bottom of the image. So the focus is out in front of you, NOT In the middle of the image which is actually high above your head.
JEDIT: In that image, not only can you see how the optical axis is NOT in the center of the frame, you can see just how much of the frame is cut off on the dome screen…
