I recently watched my official first 3d Movie, and for a good start was Avatar
I watched it twice in two differents systems, Real D and Dolby 3D.
In Real D the movie looks very good, although I was in the front left seats, I did not see any type of ghosting or artifacts.
However in Dolby 3D my 3d experience was not as good, because there was a lot of ghosting and some artifacts like a paletized rainbows, especially in dark and/or blurried scenes, for example in scennes with smoke or clouds, or scenes with parts "out of focus". I think that all of those problems was because of the glasses, because some times I took them off for a momment ad did not see any problem in the screen.
So, some of you have seen any of these problems in Dolby 3D cinemas?
