Microphotographs are photographs shrunk to microscopic scale (see microfilm) – not to be confused with photomicrographs, which are photographs of microscopic things.〔(Focal encyclopedia of photography By Michael R. Peres ) Focal Press, 2007 ISBN 9780240807409, 846 pages〕 Microphotography is the art of making such images. Other applications of microphotography include espionage such as in the Hollow Nickel Case. Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839.〔 〕 He achieved a reduction ratio of 160:1. Dancer perfected his reduction procedures with Frederick Scott Archer’s wet collodion process, developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby, and did not document his procedures. The idea that microphotography could be no more than a novelty was an opinion shared by the 1858 ''Dictionary of Photography,'' which called the process "somewhat trifling and childish."〔 Originally published in ''(Dictionary of Photography )'' (1858).〕 Novelty viewing devices such as Stanhopes were once a popular way to carry and view microphotographs.〔(Focal encyclopedia of photography By Michael R. Peres ) Focal Press, 2007 ISBN 0-240-80740-5,ISBN 978-0-240-80740-9. 846 pages〕 An important application of microphotography is in microforms. ==See also== * Microprinting 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microphotograph」の詳細全文を読む スポンサード リンク
