A lighting control apparatus comprising: a control interface configured to connect to a lighting system comprising one or more luminaires for illuminating an environment, each luminaire comprising at least one lamp controllable to emit configurable illumination; a memory configured to store at least one scene data set defining an initial lighting scene for rendering by a group of lamps in the lighting system; a scene controller coupled to the memory and arranged for controlling the group of lamps, via the control interface, to render lighting scenes; characterized by the scene controller further arranged to store, in the memory, current illumination settings for each lamp in the group of lamps, and further to update the current illumination settings whenever the settings of a lamp in the group of lamps are altered by the scene controller, such that the memory comprises the last known illumination settings of each lamp in the group of lamps; a detector configured to detect when at least one lamp of the group of lamps is emitting disruptive illumination that would disrupt the initial lighting scene by detecting, via the control interface, that the at least one lamp of the group of lamps has become unreachable and therefore uncontrollable by the scene controller; and a scene modifier coupled to the detector via the scene controller, the scene modifier being configured to determine at least one characteristic of the disruptive illumination by accessing in the memory the respective last-known illumination setting of the at least one lamp of the group of lamps, and further configured to generate, based on the determined characteristic, a modified scene data set to account for the disruptive illumination, such that a modified overall illumination of the environment when rendering a modified lighting scene defined by the modified scene data set at least approximately matches an overall illumination of the environment that would have been provided had it been possible to render the initial lighting scene without the disruptive illumination; wherein the scene controller is configured to control one or more lamps of the group of lamps, via the control interface, to render the modified lighting scene defined by the modified scene data set, wherein controlling the one or more lamps of the group of lamps comprises adjusting the illumination of the one or more lamps of the group of lamps other than the at least one lamp of the group of lamps which is uncontrollable by the scene controller. a control interface configured to connect to a lighting system comprising one or more luminaires for illuminating an environment, each luminaire comprising at least one lamp controllable to emit configurable illumination; a memory configured to store at least one scene data set defining an initial lighting scene for rendering by a group of lamps in the lighting system; a scene controller coupled to the memory and arranged for controlling the group of lamps, via the control interface, to render lighting scenes; characterized by the scene controller further arranged to store, in the memory, current illumination settings for each lamp in the group of lamps, and further to update the current illumination settings whenever the settings of a lamp in the group of lamps are altered by the scene controller, such that the memory comprises the last known illumination settings of each lamp in the group of lamps; a detector configured to detect when at least one lamp of the group of lamps is emitting disruptive illumination that would disrupt the initial lighting scene by detecting, via the control interface, that the at least one lamp of the group of lamps has become unreachable and therefore uncontrollable by the scene controller; and a scene modifier coupled to the detector via the scene controller, the scene modifier being configured to determine at least one characteristic of the disruptive illumination by accessing in the memory the respective last-known illumination setting of the at least one lamp of the group of lamps, and further configured to generate, based on the determined characteristic, a modified scene data set to account for the disruptive illumination, such that a modified overall illumination of the environment when rendering a modified lighting scene defined by the modified scene data set at least approximately matches an overall illumination of the environment that would have been provided had it been possible to render the initial lighting scene without the disruptive illumination; wherein the scene controller is configured to control one or more lamps of the group of lamps, via the control interface, to render the modified lighting scene defined by the modified scene data set, wherein controlling the one or more lamps of the group of lamps comprises adjusting the illumination of the one or more lamps of the group of lamps other than the at least one lamp of the group of lamps which is uncontrollable by the scene controller.
