Hippolyte Bayard (1801 – 1887) was a French pioneer of photography. He invented his own process that produced direct positive paper prints in the camera and presented the world’s first public exhibition of photographs on 24 June 1839. He claimed to have invented photography earlier than Daguerre in France and Talbot in England, the men traditionally credited with its invention.

While working as a civil servant, Bayard experimented with photography. He developed his own method of producing photos called the direct positive process. It involved exposing silver chloride paper to light, which turned the paper completely black. It was then soaked in potassium iodide before being exposed in a camera. After the exposure, it was washed in a bath of hyposulfite of soda and dried.

The resulting image was a unique photograph that could not be reproduced. Due to the paper’s poor light sensitivity, an exposure of approximately twelve minutes was required. Using this method of photography, still subject matter, such as buildings, were favoured. When used for photographing

Hippolyte Bayard (French pronunciation:[ipɔlitbajaʁ]; 20 January 1801 – 14 May 1887) was a French photographer and pioneer in the history of photography. He invented his own process that produced direct positive paper prints in the camera and presented the world's first public exhibition of photographs on 24 June 1839. He claimed to have invented photography earlier than Louis-Jacques Mandé Daguerre in France and William Henry Fox Talbot in England, the men traditionally credited with its invention.^[1]

Bayard experimented with the new medium taking photos of plant specimens, statuary (including posing with them for self-portraits), street scenes, urban landscapes, architectural photos, and portraits. He photographed prominent figures and an ordinary worker. He also advoca

Hippolyte Bayard

Hippolyte Bayard, born 20 January 1801 in Breteuil-sur-Noye, died 14 mai 1887 in Nemours, was the inventor of a photographic process. Since 1837 he could produce persisting photograms by means of his self-developed direct positive process^[1]. Thus he was one of the inventors of photography since its invention was officially acknowledged in 1839 by the French government, but Daguerre and Niépce named as its official inventors. Bayard applied for acknowledgement of his invention just before that official proclamation. He even organised the World's first public exhibition of photographs in the Salle des Commissaires-prisseurs in Paris, one month before the government's proclamation. But Arago, the responsible officer and member of the academy of science, neglected Bayard's efforts. 30 paper images achieved by Bayard's direct positive process were shown at the exhibition.

For his 1840 self-portrait he mimed a drowned person. This was easier for him since he could photograph himself with closed eyes - exposure time was 12 minutes. The self-portra
