Félix-Jacques Moulin, c. 1851–1854 Before 1839,
depictions of nudity and erotica generally consisted of paintings, drawings and engravings. In that year,
Louis Daguerre presented the first practical process of
photography to the
French Academy of Sciences. Unlike earlier photograph methods, his
daguerreotypes had stunning quality and did not fade with time. Artists adopted the new technology as a new way to depict the nude form, which in practice was the feminine form. In so doing, at least initially, they tried to follow the styles and traditions of the art form. Traditionally, in France, an académie was a nude study done by a painter to master the female (or male) form. Each had to be registered with the French government and approved or they could not be sold. Soon, nude photographs were being registered as académie and marketed as aids to painters. However, the realism of a photograph as opposed to the idealism of a painting made many of these intrinsically erotic. In
Nude Photography, 1840–1920, Peter Marshall notes: "In the prevailing moral climate at the time of the invention of photography, the only officially sanctioned photography of the body was for the production of artist's studies. Many of the surviving examples of daguerreotypes are clearly not in this genre but have a sensuality that clearly implies they were designed as
erotic or pornographic images". The daguerreotypes were not without drawbacks, however. The main difficulty was that they could only be reproduced by photographing the original picture since each image was an original and the all-metal process does not use
negatives. In addition, the earliest daguerreotypes had exposure times ranging from three to fifteen minutes, making them somewhat impractical for
portraiture. Unlike earlier drawings, action could not be shown. The poses that the models struck had to be held very still for a long time. Another limitation was the monochrome image that the technology could produce. Because of this, the standard pornographic image shifted from one of two or more people engaged in sex acts to a solitary woman exposing her
genitals. The cost of the process also limited the spread of the technology. Since one picture could cost a week's salary, the audience for nudes mostly consisted of artists and the upper echelon of society.
Stereoscopy was invented in 1838 and became extremely popular for daguerreotypes, including the erotic images. This technology produced a type of
three dimensional view that suited erotic images quite well. Although thousands of erotic daguerreotypes were created, only around 800 are known to survive; however, their uniqueness and expense meant that they were once the toys of rich men. Due to their rarity, the works can sell for more than £GB 10,000. This invention permitted an almost limitless number of prints to be produced from a glass negative. The technology also reduced the exposure time and made possible a true mass market for low cost commercial photography. The technology was immediately employed to reproduce nude portraits, classified by the standards of the time as pornographic. Paris soon became the centre of this trade. In 1848 only thirteen photography studios existed in Paris; by 1860, there were over 400. Most of them made income from the sale of illicit nude images to the masses who could now afford it. The pictures were also sold near
train stations, by traveling salesmen and women in the streets who hid them under their dresses. They were often produced in sets (of four, eight or twelve), and exported internationally, mainly to England and the United States. Both the models and the photographers were commonly from the working class, and the artistic model excuse was increasingly hard to use. By 1855, no more photographic nudes were being registered as académie, and the business had gone underground to escape prosecution. ==French influence==
