Auguste Belloc (1800–1867) was a French photographer, known for his erotic works. He was born in Montrabé, and died in Paris. Belloc began his career as a painter of miniatures and watercolors. Belloc's first photographic studio was mentioned in 1851. Auguste Belloc practiced daguerreotype, he became involved in wet collodion development and improved the wax coating process, helping the photos to keep their wet-like luster. Belloc led also important research about color stereoscopy (3-dimensional photography).

Auguste Belloc, born in Paris in 1800, was a portrait miniaturist and watercolor painter. By 1851, Belloc was making portraits with the daguerreotype and calotype processes. He was one of the founding members of the Société Française de Photographie. In the mid 1850’s, he was inventing, manufacturing and selling photographic supplies and equipment, which he continued until his death in 1867. In 1869, Marconi reproduced and published Belloc’s exquisite nudes, which were deemed pornographic at the time.
