Calotype or talbotype is an early photographic process introduced by William Henry Fox Talbot in 1841 using silver iodide coated paper. The word calotype comes from the Ancient Greek καλός, « beautiful » and τύπος, « impression ».

What does calotype in photography mean?

describe: The original negative and positive process invented by William Henry Fox Talbot, calotype is sometimes called « Talbotype ». This process uses a paper negative to produce a softer, less sharp photo than a daguerreotype, but since a negative is created, it is possible to make multiple…

What does the calotype process mean?

Calotype, also known as talbotype, William’s invention of early photography Henry Fox Talbot of England in the 1830s. In this technique, a piece of paper coated with silver chloride is exposed in a dark box. Those areas that are hit by the light are darkened in tone, producing a negative image.

How do you do a calotype?

To generate a calotype, Talbot creates a photosensitive surface by coating a sheet of paper (usually writing paper) with a solution of silver nitrate. He dries the paper to a certain extent and then coats it with potassium iodide to produce silver iodide.
