Any rapid change in the illuminance level on a given plane will cause camera exposure inconsistencies. During a fast-moving football match, it is unrealistic to expect the camera settings to be consistently changed successfully when the camera and the subject are both moving rapidly. The MAUR is used to ensure greater consistency in camera exposure and therefore give the camera operator greater freedom to provide dynamic pictures. The difference between the illuminance values of any two adjacent points on any given plane in any direction should be no greater than the permitted level stipulated in the tables in UEFA illuminance requirements. The requirement takes the form of a minimum permissible ratio between the two points and assesses illuminance values that are lower or greater than the primary reference point.
