Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. The rendered composite image may be subjected to a varying field of illumination, generated, for example, by a switched sequence of individually activated, differing illuminants. This sequenced array of illuminants causes a corresponding sequence of source images to be recovered in rapid succession, thus imparting a sense of change, such as motion, between or within the recovered source images.
