Anotations

Scope note:

Negatives on paper made by William Henry Fox Talbot's patented calotype process, a developing-out process. Distinguished from Talbot's "photogenic drawings," in which the image was printed out. For most prints made from these negatives, use "calotype prints (positive prints)." In the mid-20th century, the term was sometimes used incorrectly for all other paper negatives or salted paper prints.
