1) Who created the first photograph? How was this done?
The eldest photograph that we have access to is called "<em>View from the Window at Le Gras</em>" and it is dated around 1826-1827. It was taken by Nicéphore Niépce, a French inventor, in his residence called Le Gras (thus the name of the photo).
