Calotype
Early photographic process / From Wikipedia, the free encyclopedia
For "hot type", see hot metal typesetting.
Calotype or talbotype is an early photographic process introduced in 1841 by William Henry Fox Talbot,[1] using paper[2] coated with silver iodide. Paper texture effects in calotype photography limit the ability of this early process to record low contrast details and textures.

The term calotype comes from the Ancient Greek καλός (kalos), "beautiful", and τύπος (typos), "impression".
