?Where and when were the oldest photographs of humans taken
Boulevard du Temple
Although drawing or sculpting pictures of humans on the walls of caves is an ancient tradition that has accompanied human culture for thousands of years, the first photograph of humans was taken in 1838, specifically on Boulevard du Temple in France, and it shows two men, one polishing the other’s shoes.
At that time, Louis Dager, the French painter and inventor, took a picture of the Boulevard du Tempel using a new technique that he had invented himself a year earlier and was later called “dagger” in honor of its inventor. It was the first successful technique for taking pictures that could remain stable for a long time.
Louis Dager used silvered metal plates and exposed them to iodine vapor to make them more sensitive to light. He then put them in a camera and took pictures of the objects. This technique required 15 to 30 minutes of time to take each picture, which made it suitable for photographing still objects only.
Dager took his immortal photo from the Boulevard du Temple using his slow motion technique, which made the full street appear to be devoid of pedestrians. However, the two men at the bottom left of the photo, who had been stationary for a long time because they were busy polishing one of them’s shoes, remained immortal in the oldest photograph in which humans appear.
The stable and the pigeons' nest
Although Dagger's photo is the oldest photo showing humans, it is not the oldest photo in the history of photography. The French photographer and inventor, Joseph Nyssa-Four-Niépce, had taken the first photograph 12 years before Dagger's photograph. In 1826, Ness-Four-Niépce took a photograph of a stable and a pigeon's nest in Saint-Loup-de-Varnes in the Bourgogne region of France, which is the first and oldest photograph ever.
