Shot above is enhanced... original is shown in the two shots below. Talk about archival quality.Exposure time was eight hours on a polished pewter plate coated with bitumen of Judea (a kind of asphalt). After the exposure the plate was removed and the latent image was rendered visible by washing it with a mixture of oil of lavender and white petroleum which dissolved away the parts of the bitumen which had not been hardened by light. The photograph which Niepce called a "Heliograph" is now in the collection of the University of Texas at Austin.
Below.... the first photograph of a person? Due to the very long exposures involved in making the early photographs, there exist almost no early pictures with people in them. The image below of the Boulevard du Temple in Paris was a ten-minute exposure of the street scene in April or May of 1838. Although there was probably much traffic both pedestrian and vehicular on the Boulevard the length of the exposure meant that anything moving would not be recorded. The exception is the man standing on the corner apparently getting his boots shined.... he stood still long enough to become a part of pictorial history.
The above image is a a Daguerrotype a metal plate coated with silver halide that, after exposure, was placed over a lightly heated cup of mercury which revealed the latent image.

The process was patented in 1839. Is this the first photograph of a living person? It certainly is for now. I can just imagine trying to photograph a two year old with a ten-minute exposure. Thank the Lord for digital.
