Abstract:
1. A method of dynamically adjusting luminance of a cinematic film, the method comprising: receiving a master copy of a cinematic film that was viewed at a review cinema at a first luminance level; receiving metadata comprising at least a minimum luminance level and a maximum luminance level of the master copy of the cinematic film; receiving measurements relating to at least one optical characteristic of a viewing location, wherein the viewing location is different than the review cinema, wherein the at least one optical characteristic comprises one or more of a maximum luminance of the viewing location and a minimum luminance of the viewing location; based on at least the at least one optical characteristic and prior to use by a projector associated with the viewing location, modifying the master copy of the cinematic film so that the luminance levels of the modified cinematic film, when viewed at the viewing location, are perceptually substantially the same as the luminance levels of the master copy of the cinematic film, when viewed at the review cinema, such that the modified master copy of the cinematic film may be used by the projector without modification.
