Shedding Light on the Darkness 

Monday, May 30th, 2011

Around the country, new digital projectors are being used to screen both 2-D and 3-D movies. This should be just fine, but all too often when viewing a 2-D movie, customers are being subjected to an overly-dark image. Ty Burr has written an excellent article on the issue. A big part of the problem is the use of 3-D polarizing lenses which wind up filtering out a huge chunk of the light, even for 2-D movies.

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.”
