Poor Picture At Your Local Cinema?
The Hub writes "Have you ever noticed that the picture in your local movie theater is too dark or grainy? The Boston Globe does some good ol' fashioned investigative reporting to find the culprit. Apparently, the cause is linked to some 3D digital projectors requiring a technically challenging lens switch for 2D movies that sometimes doesn't happen."
This is actually due to the fact that Sony digital projectors are so locked down with DRM that even changing the lens requires all kinds of password checks (which can potentially lock the camera down if not done correctly).
Sadly, this is one of the problems that digital projectors were *supposed* to fix. For years, it was a infamous practice for theater managers to extend projector bulb life by reducing the power of the lamp. Since most people don't notice (having no idea how the movie is *supposed* to look), they could get away with it. Roger Ebert in particular complained about this practice for decades (even organizing protests at certain theaters engaging in the practice). When digital projection came along, one of the selling points was that it produced a much more consistent image (and managers couldn't futz with it--reducing bulb strength, etc.).
Now, thanks to our good friends at Sony, it would seem like we're right back where we started from (maybe even worse, since this produces an even darker image than one of the celluloid projectors at half power).

why passwords and such are needed to change the lens and how was it set up like that?
The 3-D lens is mounted inside the case. The password is needed to allow you to open the case, because once the case is open you could get at the digital signal and steal it.
Why they coupled these is a small mystery, the most likely solution to which is that Sony's engineers did what was easy to implement instead of what was easy to use.
