First Picture Ever Taken
The problem to fix the image to the medium had remained unsolved until Joseph Niepce successfully created the first Photograph using a pewter plate coated with bitumen. He later worked with Louis Daguerre to reduce the long exposure times.
Photography On Paper
Let us now look at some of the notable early works directed towards having a photographic image on paper.
The Improved Daguerreotype
The original Daguerre’s process had very slow speed, with exposure times of more than 20 minutes. This made it unsuitable for portraiture. It was only used for still life photography and landscape imagery.
