Study Notes
Daguerreotype Process
- A copper sheet is plated with silver, then polished to a mirror finish.
- The plate is sensitized in a light-tight box with iodine and bromine vapors, turning the surface yellow.
- The reaction of iodine vapor with silver creates light-sensitive silver iodide.
- The sensitized plate is then exposed in a camera.
- Development involves exposing the plate to heated mercury fumes, creating a milky white image.
- The mercury amalgamates with silver to form the image.
- Fixing the image uses a solution of sodium chloride (table salt) or sodium thiosulfate (hypo).
- The image is intensified by treating it with gold chloride.
- The final step involves washing the plate with distilled water and drying.
