when photography invented

The two Frenchmen Nicéphore Niepce and Louis Daguerre who is on featured image are considered the discoverers of photography. They developed the first techniques and chemical processes that made it possible to capture images.

This was followed by decades of continuous technical development.
With the introduction of the first Kodak camera in 1889, the development reached a level that could essentially continue to this day. It was only electronics and finally digitalization that produced new photographic processes.
