The process of woodburytype is photomechanical rather than photographic, because sensitivity to light plays no role in the actual printing. It happens when a sheet of gelatin is exposed to UV-rich light through a photographic negative, causing the gelatin to harden. Then it is soaked in water to dissolve the hardened gelatin. The image is then pressed into a thick sheet of lead. That creates a mold that is filled with liquid pigmented gelatin and a piece of paper is then pressed down onto it.

Daguerreotype
To make a daguerreotype, first you will want to polish and buff a silver-coated copper plate. Then expose the plate to iodine and bromine fumes, to sensitize it. Put the plate into the camera and hold the subject in front of the camera.
