A method of controlling a lighting system comprising at least two luminaires arranged to illuminate a physical space, to render a version of a selected scene image. The method comprising: capturing at least one image of the physical space; using the captured at least one image to determine, for each of the luminaires, at least one location in the physical space associated with that luminaire; receiving a selection of a scene image to be rendered; processing the selected scene image to select at least two colors in the scene image and determining a respective location of each selected color in the scene image; comparing the determined scene image locations with the determined luminaire locations so as to identify, for each of the determined scene image locations, a matching one of the determined locations in the physical space; and controlling the luminaires to render the scene image, based on said comparison.
