Circular prints made in Kodak roll film cameras became popular with the general
public because of their simplicity of use. Kodak's slogan was "You press
the button, we do the rest." The Eastman Kodak pre loaded 100 exposure
roll film camera eliminated the use of chemicals and preparations by the photographer.
The camera with exposed film was sent to Eastman Kodak for processing. The
Eastman Kodak products contributed to the emergence of amateur photography
at the end of the 19th century.
1842 - Present.
Invented by Sr. John Herschel in 1842, The cyanotype is named for its rich
blue-green hue. They are produced by light sensitive iron salts. Cyanotype
prints have no emulsion; the light-sensitive iron salts have been infused into
the paper fibers. Cyanotypes are relatively inexpensive and easy to make. They
were a favorite of amateur photographers in the mid-1880s. The cyanotype process
has remained virtually unchanged since its invention.
