"Though why, of course, you'd want to waste all of the toner is beyond me," Dr. Whoobint of the Palo Alto Institute for Really Useless Things commented. "You might as well use paint."The image represents an advance in photographic technology, also, as each pixel corresponds to a real-world space about the width of a photon at the shutter aperture. In other words, Dr. Whoobint explained, "this picture contains absolutely all of the resolution that it's going to get."The Palo Alto image is the very largest a JPEG image can legally be. "."
