A paper negative, also known as a talbot-type in which a negative image is produced on paper, then contact printed with another light sensitive piece of paper to create a positive.

Introduced by William Henry Fox Talbot in 1841, the initial image produced was monochromatic, tonally and laterally reversed – as a negative.

When placed in contact with another chemically treated surface and exposed to sunlight, the negative image was transferred in reverse – a positive.
