Salted paper prints were created from photogenic drawing negatives, calotype negatives, paper negatives, and eventually glass plate negatives. Salted paper prints produced from paper-based negatives have a grainy appearance. Even those printed from waxed paper negatives, which make paper fibers less visible, exhibit some paper fibers.
Photographers experimented in various ways to create a sharper image using glass plate negatives. Early attempts included crystalotypes, introduced by John Adams Whipple, in which salted paper prints were created from albumen on glass negatives. While the process resulted in images with finer detail, it proved to be a complicated one. By the early 1850s, the majority of salted paper prints were produced from collodion on glass negatives. The smooth surface and high resolution of the collodion plates rendered far sharper prints than those made from paper-based negatives.
