An early daguerrotype, from 1838, taken by the man himself, Louis Daguerre:
From Wikipedia (where you can see a larger image):
Boulevard du Temple, Paris, 3rd arrondissement, Daguerreotype. The purportedly first picture of a living person. The image shows a busy street, but due to exposure time of more than ten minutes, the traffic was moving too much to appear. The exceptions are the two people at the bottom left, one who stood still getting his boots polished by the other long enough to show. Look closely and you will also see another man sitting on a bench to the right reading a newspaper. Also in the upper left hand side you can also see another man standing under the awning of the 3rd building from the left. What looks to be a woman standing under the street lantern at 10 o'clock from the man getting his shoes shined and another one in the big white building,1st row 3rd window down. Notice the child in the top floor window of the white building in front. Note that the image is a mirror image.
