Summary
portrait a man with a child
The daguerreotype method of the photographic process was invented by Louis Daguerre in the 1830s. It was the first photographic process and it was widely used in the mid-19th century. The process involves exposing a silver-coated copper plate to light in a camera, which then creates an inverted, highly detailed image on the plate. The plate is then treated with chemicals to make the image visible and fixed in place.
The daguerreotype is a photographic process invented by the Parisian inventor and entrepreneur Louis Jacques Mandé Daguerre (1787-1851) who was the first person to publicly announce a successful method of capturing images. His invention was an immediate hit, and France was soon gripped by ‘daguerreotypomania’. Daguerre released his formula and anyone was free to use it without paying a license fee – except in Britain, where he had secured a patent. Daguerreotypes required a subject to remain still for several minutes to ensure that the image would not blur.
