The Imagen del Bulavar du Temple, obtained by Daguerre in 1838, is considered the first photograph in history.

The process consisted of fixing an image using silver bromide, which was dispersed on a heated base of common salt and exposed to mercury vapor, which disappeared after a certain amount of time. An innovation that Daguerre contributed was to submerge the plancha in a solution that would stabilize the image.

In 1838, Daguerre visited the Boulevard du Temple with the exhibition nearby at 10 minutes. This picture is considered to be the first picture. Photographs of a boot cleaner and his client are seen. Prior to this, Lewis had experimented with other scenes of Paris and with various bodegons.
