Methods and apparatus are provided for forming an image (68) of a scene (18) comprising a source of emitted or reflected light. The scene is illuminated (54) and a first image corresponding to the illuminated scene is recorded. Illumination is ceased, and a second image of the emitted or reflected light, corresponding to the non-illuminated scene, is recorded. The second image is used to generate a marker in the first image, said marker indicating the position of the emitted or reflected light.
