Imax vs Dolby Vision



I was asked over the holiday which is the better one, IMAX® and Dolby Cinema™. I'm not going to compare 3D options in these two, but let's look at what you can expect from your money. In both cases, the experience is being managed and guaranteed by the license holder, so you are guaranteed a good experience regardless.

I'm also going to compare two versions of IMAX® because they have been around for a while and this means you could end up in a film version of the cinema. The Dolby™cinemas are newer and are a partnership with Christie, so they are digital.

So in summary, when they both show you their promo video before the movie...


I do believe the white dot showing black in Dolby Cinema™, just wins for me...
