The scientific knowledge of cameras was known long before the 19th century actually, in the form of camera obscura, literally meaning ‘dark room’ in Latin (at least according to Wikipedia), because the camera was an actual small, dark room with a tiny hole or lens. It was Louis Daguerre who in 1837, created the world’s first photographic camera. His invention reduced the exposure time of photographs from 8 hours to 30 minutes. When his invention was announced, it very quickly moved thorough the Europe, in a time when the industrial revolution was starting to take hold, Daguerre’s ‘daguerreotypes’ quickly began being perfected and produced in several industrial nations. By the 1840s, photography studios started to pop up in England, and by the 1880s, the invention of film rolls made photographs cheaper and more accessible. For the first time now, art was democratic, to have a portrait of oneself wasn’t exclusive to the wealthy but an occasional spending of the middle and lower classes too.
