It’s the birthday of the man who helped invent the art of photography, Louis Daguerre, born just outside of Paris, France (1789), who started out as a theater designer, using hand-painted translucent screens and elaborate lighting effects to create the illusion of a sunrise or a sudden storm onstage.
But in 1829, he learned about a new technology that made it possible to use light to capture an image on a metal plate, though the quality of the image was poor. Daguerre set out to improve the process, and he came up with a combination of copper plate coated with silver salts that could be developed with the application of mercury vapor and table salt.
He first used this process to capture a series of images of Paris, including pictures of the Louvre and Notre Dame. The camera needed about 15 minutes exposure time to capture an image, so most of Daguerre’s early pictures don’t show any people. The one exception is a picture of a boulevard that shows a man in the foreground who has stopped to shine his shoes. He was the first human being ever caught on film.
Daguerre announced his invention in 1839, and the images he produced became known as daguerreotypes.
