Initially Iodine, later found Bromine and Chlorine made the surface more sensitive.

Exposed plate held over heated vat of Mercury, the vapors of which converted the silver that had been exposed to soluble form that could be washed away. The remaining silver remains, black in tone, on the plate.

Image is then “fixed” with a solution of hyposulphite of soda, which removes any unexposed halides on the plate.

Calotype
William Fox Talbot, 1841
Calotype
Similar to daguerreotype, in that Silver Iodine was used as a sensitizing agent.
However, solution applied to paper, as opposed to metallic plate.

Calotype
Similar to daguerreotype, in that Silver Iodine was used as a sensitizing agent.
However, solution applied to paper, as opposed to metallic plate.
Primary advantage of this:Produced a paper negative, from which reproductions could more easily be
made.
