It must have been an incredible feeling for Joseph Nicéphore Niépce and Louis Jacques Mandé Daguerre when, between 1820 and 1840, they successfully developed the correct chemical process to reproduce an image seen through their own eyes onto a metallic plate. This had to be a feeling comparable to the big bang; not only an emotional explosion, but a social explosion as well. This analog extension of vision put freehand visual art, created through sketching or painting, at risk; it revolutionized arts, literature, visual information, and communication; as well as developing into cinema, television, and video.
For decades, other scientists have been developing the next evolution of those first chemical experiments, such as the 3D laser scanner. The American designer, Scott Page, is one of the pioneers of the use of this technology. With his 24 lb. laser scanner, he scanned various buildings in San Francisco.
