14 feb 1841 año - William Henry Fox Talbot develops the negative-positive process

Descripción:

The process is called a Calotype or sometimes a Talbotype. This process uses a paper negative to make a print with a softer, less sharp image than the daguerreotype, but because a negative is produced, it is possible to make multiple copies. The image is contained in the fabric of the paper rather than on the surface, so the paper fibers tend to show through the prints.
