Beside this, is IMAX worth the extra money?
Digital IMAX uses 2K and 4K resolution image projections which is at much lower resolution than the tradition IMAX film. If you're talking about a movie that has been at least repurposed and remastered for IMAX viewing or, even better, shot directly with IMAX cameras, those are certainly worth the extra pennies.
Furthermore, what is the advantage of IMAX? There's its geometry, putting you closer to the picture and closer to the action. You won't find a “bad seat” in an IMAX theatre. There's also the bigger, wider, higher curved screen; the heart-thumping sound system; the feeling that you're part of the picture, not just looking through a window at it.
Beside above, what is better IMAX or Dolby?
Dolby Cinema projects better images with 500 times higher contrast ratio and four times more resolution than IMAX. On the other hand, IMAX uses 40% larger screens and a 26% taller aspect ratio as compared to Dolby Cinema. Both use dual 4k laser projectors and an upgraded sound system for a more immersive experience.
Which is better Imax or RPX?
As I said before, IMAX lets the audience sit much closer to the screen, while RPX is illuminated with a decent sound system and a giant screen. Meanwhile, IMAX ratio is around 1.90:1, which equals to 17x9.So compared to IMAX, RPX owns the screen that is much bigger than that of dual digital IMAX.
