Printmaking and photography are processes that allow for mass production and circulation of images. Printmaking involves transferring an image from a matrix to a surface through various techniques like woodcut, etching, lithography, and screenprinting. Photography captures images through the action of light on a light-sensitive surface. Early photographic processes included daguerreotypes and wet plate collodion images. The invention of film and cameras like the Kodak Brownie made photography more accessible. Both printmaking and photography have been used experimentally and to circulate political, social, and artistic messages to wide audiences.
