Cinema chains dimming movies “up to 85%” on digital projectors
It’s been reported that AMC, National Amusements and Regal Cinema chains are leaving 3D projector lenses on for 2D movies. This means that the projected image is polarized and far dimmer than it should be. The 3 chains are mum but an insider, speaking on condition of anonymity, says it’s “unspoken” corporate policy.
Delving deeper, a possible reason for this is it’s too much work after each film to accurately swap lenses but also because a certain security feature could be disabled; DRM (or Digital Rights Management) that is the bane of privacy issues to most internet users.
