Noticed this on sunday for the first time at Telford Imax prior to watching Independence Day 2. Not sure why they were fuzzy but I suspect something similar to this was going on. They left a 3d lens on to display a couple of 2d trailers. The edges around peoples faces were blurred with purple fringing and not in focus. The trailers either looked like a low quality 3d to 2d conversion or the lens for the main feature, which was in 3d was left on to show the (2d) trailers:
So why aren’t theater personnel simply removing the 3-D lenses? The answer is that it takes time, it costs money, and it requires technical know-how above the level of the average multiplex employee. James Bond, a Chicago-based projection guru who serves as technical expert for Roger Ebert’s Ebertfest, said issues with the Sonys are more than mechanical. Opening the projector alone involves security clearances and Internet passwords, “and if you don’t do it right, the machine will shut down on you.’’ The result, in his view, is that often the lens change isn’t made and “audiences are getting shortchanged.’’
