Define "composite." If by composite you mean composed of images shot through red green and blue filters, then I have news for you. Every digital photograph you have ever taken with a digital camera is a composite. They all use pixels filtered for various colors of light and then combine those images. In consumer cameras this process is hidden from the user and done internally in the camera. The images I linked to are a "composite" in that sense, but so are the images from the cell phone in your pocket.
