I came across this word in The Fifth Child by Doris Lessing.
da·guerre·o·type (d-gâr-tp) n.
1. An early photographic process with the image made on a light-sensitive silver-coated metallic plate.
2. A photograph made by this process.
tr.v. da·guerre·o·typed, da·guerre·o·typ·ing, da·guerre·o·types
To make a daguerreotype of.
Isn't that a nice one?
