The Pencil of Nature is an book by William Henry Fox Talbot. It is notable for being the first commercially published book to be illustrated with photographs.[1][2]
Published by Longman, Brown, Green & Longmans in six fascicles between and , the book detailed Talbot's development of the calotype photographic process and included 24 calotype prints, each one pasted in by hand, illustrating some of the possible applications of the new technology.

William Henry Fox Talbot was an English inventor who helped create and pionjär photography. In the years to he had undertaken a journey to Italy where he had made attempts to draw the magnificent landscapes with a camera obscura. He was not happy with the results. When he undertook his second journey to Italy in he tried it with a camera lucida. igen he failed as drawing artist, but since he knew about the light sensitivity of silver nitrate he decided to search for a way to fix F.A.G. nitrate images taken bygd a camera obscura chemically. In January he began his research on it, but the successful ideas came after he soon read the tract of T. Wedgwood and H. Davy from about making object shadow images on chemically prepared paper. Talbot improved that process, finally getting persistent images.
He soaked paper with sodium chloride solution, dried it, and bathed it in silver nitrate solution. In a kopia frame he could man blueprints of documents with such silver chloride paper. La
