USA Today a écrit :Cameron says to “do it right”, that it should take six months to a year to convert a film to 3D in post production. He mentions the 3D conversion of Clash of the Titans is taking eight weeks. He says that Hollywood is ignoring “the fact that we natively authored the film in 3D, and decide that what we accomplished in several years of production could be done in an eight week (post-production 3D) conversion.” Cameron warns that “if people put bad 3D in the marketplace they’re going to hold back or even threaten the emerging of 3D. People will be confused by differences in quality. … Because the audience doesn’t know the difference — when they put on the glasses on, they don’t know if the problem is in the glasses, the TV or the actual way in which the stereo space is managed by the producers of the film.”
