I've seen Avatar twice at my local cinema which has a Dolby 3D system and want to see it one more time during its run in theaters. Another cinema nearby is showing it IMAX 3D which I'm really excited about because walking out of the theater I was thinking that this movie is one of the few that would really benefit from IMAX. However I've seen IMAX 3D movies in the past and was really disappointed. There has always been problems with ghosting and distortion, I've walked out of the theater with terrible headaches, and so on. But I haven't been to see an IMAX 3D film since before Real D appeared on the scene. Does anyone know if IMAX uses the newer 3D technology or if they are still using older linear polarization setups?
