The first photographic process or heliography was invented around 1824 by NicephoreNiépce.Images were obtained with Judea bitumen spread on a silver plate after an exposure time of many days.

In 1829, Niépce associated Louis Jacques Mande Daguerre to his research.

In 1832, they put the last touch, using a residue of lavender oil distillation, a second process producing images in a one day exposure time.

In 1833 Niépce died, Daguerre went on working alone and invented, in 1838, the daguerreotype, the first process including a development stage.

A silver plate coated with a very thin silver iodide layer was exposed in a camera obscura then exposed to mercury vapors that induced the apparition of the invisible latent image that had been formed during the exposure to light.

This development was in fact such an amplification of the effect of light that the exposure time was hardly more than 30 minutes.

Fixing was done by immersing the plate in sea salted water. In July 1839, another frenchman, Hippolyte Bayard, discovered the way to obtain positive images directly on paper.

A sheet of paper covered with silver chloride was blackened by light then exposed in a camera obscura after being sensitized in silver iodide.
