Take a look at this photograph.
At first it might appear slightly interesting, a black and white photo, clearly from many decades ago. But this photograph is special because of its timing. This was taken way back in 1838, by Louis Daguerre as he was experimenting with the process to record images. It is of the Boulevard du Temple in Paris, and is one of the first photographs ever taken. Now the streets of Paris were not as empty as they appear here. Early photographs had to be exposed for several minutes (over ten for this one) to collect enough light, so anything that is not completely still for that time becomes a blur, and anything moving faster than a snail is invisible. Notice how blurry the trees are compared to buildings or streetlamps. This street was probably busy, but the moving people and carriages blended into the background. Except in the lower left. Let me zoom in.
A shoeshine and his customer were still enough to be captured in this photograph. That makes this the earliest photograph of a person. Let me repeat that: Above is the very first photograph of a human being. Just something to think about.
