A daguerreotype is an early kind of photograph from the 1800s, or the method of making it. The picture sat on a polished silver-coated copper plate, not on paper. Tilt it, and the face can vanish into the shine, like a small mirror that also holds a ghost. Each plate was one of a kind — you could not print copies the way we print photos now. People had to sit very still, because the plate needed a lot of light. You will see them in museums and old family boxes, and when someone talks about the birth of photography. The word is historical and a little formal; nobody with a phone says they took a daguerreotype.

- 1
An early type of photograph created by exposing a silver surface which has previously been exposed to either iodine vapor or iodine and bromine vapors; such a photograph.
- The awakening of science to this new way of seeing the cosmos began with Johann Ritter in 1801. By 1815, scientists found that Ritter's “chemical rays” [ultraviolet rays] darkened not just silver chloride but also many other kinds of metallic salts. Between 1826 and 1837, Nicéphore Niépce, credited with taking the first successful photograph, in 1827, and Louis Daguerre, the most famous photographic innovator of his day, found that silver iodide was especially light sensitive, and they used this discovery as the basis for their early work, which even then had begun to gain international notice. By 1842, others found that when sunlight hit a gelatin emulsion containing silver iodide, soon to be called a daguerreotype plate, it induced a photochemical reaction. Practical photography was born.
