But first something about the history of photography [text in german]:

The first photograph was made in 1826 by Joseph Nicéphore Niépce. In 1837, Louis Jacques Mandé Daguerre used a better method based on the development of the photos with the help of mercury vapor and subsequent fixation in a hot saline solution or a normalized sodium thiosulfate solution. The pictures produced in this way, all unique on silver-plated copper plates, were called daguerreotypes. As early as 1835, the Englishman William Fox Talbot invented the negative-positive method.
With the introduction of the negative-positive method, a duplication in the contact method was also possible. The size of the finished photo corresponded in both cases to the recording format, which usually required very large, unwieldy cameras. With the roll film and in particular the Kleinbildkamera, which was developed by Oskar Barnack at Leica and introduced in 1925, which used the conventional 35 mm Kinofilm, completely new possibilities for mobile, fast photography emerged. Although, due to the small format, additional devices were required for enlargement, and the image quality with the large formats was far from able to keep up, the Kleinbild in most areas of photography as a standard format prevailed.

In the middle of the 19th century, the new self-awareness of the bourgeoisie is reflected in the popularity of portrait photography. The new technology provided the opportunity for broad sections of the population to step out of anonymity by means of portraits and group photographs - something which until now had been reserved for the well-to-do nobility. The photographing of people required tremendous discipline and endurance from both the photographer and the photographer. The enormously long exposure times, which gradually disappeared through ever more powerful lenses, rFoto: Dörte Kleylingequired their own devices to fix the photographers.
Early portrait photographs were made by Hermann Biow, who used the technique of daguerreotype. He opened his studio in Hamburg in 1841 and portrayed politicians, celebrities and wealthy citizens. André Adolphe-Eugène Disdéri developed a business development of the portrait photography from 1854 onwards, small portraits in the business card format, which he created with his own technique. Subsequently, numerous portrait studios emerge, which are particularly frequented by the middle class bourgeoisie. There is a repression of the work of portrait painters.
