Being a cloth merchant by trade, in the 1840s he developed interest in photography and focused on technical and economical issues of mass production of photo prints.

[2] After Louis Daguerre solved the problem of long exposure time and introduced daguerreotypy, a practical photographic process, to the general public in 1839, Blanquart-Evrard developed interest in photography.

[3][4] In January 1847, he presented his research on stabilizing the photo prints by floating them in the silver solution to the French Academy of Sciences.

[6] Blanquart-Évrard introduced to public the work of many pioneering European photographers, such as Édouard Loydreau (1820–1905), Charles Marville (1813–1879), Ernest Benecke (1817–1894), Thomas Sutton (1819–1875), and Maxime Du Camp (1822–1894).

Also, due to technology deficiency, photo prints were fading with time and Blanquart-Evrard's business venture had to close in 1855, losing in competition with lithographs.
