In the 1850s, the British named John Benjamin Dancer succeeded in making a series of photographs in extremely small sizes. One of these, Queen Victoria’s family, was seen by all the individuals. Dancer put this photograph under the stone of a wedding ring. The stone functioned as a magnifying glass, and the photograph could easily be selected with the naked eye. When Paris was besieged during the Franco-Prussian War in the 1870s, the “message” over the hundreds of microfilms attached to the feet of the mail pigeons was sent out of Paris. In 1927, in the US, Kodak began marketing microfilm photographic machines to record documents such as bank checks. Share Info
