Abstract
A method of chromakey recording, which includes providing, in a scene, a chromakey material which is capable of continued luminance without activating light. The chromakey material is activated and the scene is recorded without activating light while the chromakey material is luminescing. The chromakey material may be an electroluminescent material that is activated by applying electrical energy to the chromakey material. The chromakey material may also be a phosphorescent material, which is activated by applying light to the phosphorescent material. The light is removed from the phosphorescent material during recording.
