World’s oldest photography
I found a little gem; The world's oldest photography, taken by Nicéphore Niépce 186 years ago, in 1826.
Notice the light being cast from both sides, so you can see the buildings being lit from the left and from the right. This is due to the 8-hour exposure of this photo.
Nicéphore was clearly a clever guy. His other inventions included the Pyréolophore, which is probably the first internal combustion engine, invented 1807. That year it powered a boat upstream on the river Saone.
