Our normal expectations of photography tend to focus on the instancy of the process. A photo is a snapshot, a frozen slice of time measured in fractions of a second.
This particular photograph is different. It was made over a much longer duration. Look to the bottom-left of the frame. There is a man having his shoes shined. That man — this picture — is the earliest known photograph of a recognisable human being. It was taken in Paris, France, in 1838 by Louis Daguerre.
